117-457: Since the 1980s, the term chronograph has also been applied to all digital watches that incorporate a stopwatch function. The term chronograph comes from the Greek χρονογράφος ( khronográphos 'time recording'), from χρόνος ( khrónos 'time') and γράφω ( gráphō 'to write'). Early versions of the chronograph are the only ones that actually used any "writing": marking the dial with

234-414: A holding company in 2001 and was renamed Seiko Holdings Corporation on July 1, 2007. Seiko Holdings Corporation was renamed Seiko Group Corporation as of October 1, 2022. Seiko watches were originally produced by two different Hattori family companies (not subsidiaries of K. Hattori & Co); one was Daini Seikosha Co. (now known as Seiko Instruments Inc., a subsidiary of Seiko Holdings since 2009) and

351-400: A pocket , often attached to a chain. A stopwatch is a watch that measures intervals of time. Watches appeared in the 16th century. During most of its history, the watch was a mechanical device, driven by clockwork , powered by winding a mainspring , and keeping time with an oscillating balance wheel . These are called mechanical watches . In the 1960s the electronic quartz watch

468-582: A "Watch Wristlet" design in 1893, but probably produced similar designs from the 1880s. Officers in the British Army began using wristwatches during colonial military campaigns in the 1880s, such as during the Anglo-Burma War of 1885. During the First Boer War of 1880–1881, the importance of coordinating troop movements and synchronizing attacks against highly mobile Boer insurgents became paramount, and

585-572: A blend of both. Most watches intended mainly for timekeeping today have electronic movements, with mechanical hands on the watch face indicating the time. Compared to electronic movements, mechanical watches are less accurate, often with errors of seconds per day; are sensitive to position, temperature, and magnetism; are costly to produce; require regular maintenance and adjustments; and are more prone to failures. Nevertheless, mechanical watches attract interest from consumers, particularly among watch collectors. Skeleton watches are designed to display

702-590: A building with a clock tower (16 meters from top to bottom), setting up shop at the new address. Seiko launched its first in-house pocket watch, the Timekeeper, in 1895; the first Japanese-made wristwatch, the Laurel, in 1913; and the first Seiko-branded wristwatch in 1924. In order to avoid an ill omen believed to be associated with the word "GLORY" in Japanese, Seikosha changed its trade mark to "Seiko" in 1924. In 1929,

819-424: A decade – almost 100 years of dominance by the mechanical wristwatch legacy. Modern quartz movements are produced in very large quantities, and even the cheapest wristwatches typically have quartz movements. Whereas mechanical movements can typically be off by several seconds a day, an inexpensive quartz movement in a child's wristwatch may still be accurate to within half a second per day – ten times more accurate than

936-479: A great-grandson of Seiko's founder, became Seiko Watch Company's president and CEO and felt that Seiko should raise its perceived image outside Japan. In management's view, Seiko could claim distinction as the only 'mechatronic manufacturer' in the world – a vertically integrated watchmaker that excelled in both mechanical watchmaking and micro-electronics." Seiko Corporation of America distributes Seiko watches and clocks, as well as Pulsar and Lorus brand watches, in

1053-424: A leather strap, but by the early 20th century, manufacturers began producing purpose-built wristwatches. The Swiss company Dimier Frères & Cie patented a wristwatch design with the now standard wire lugs in 1903. In 1904, Louis Cartier produced a wristwatch to allow his friend Alberto Santos-Dumont to check flight performance in his airship while keeping both hands on the controls as this proved difficult with

1170-471: A line of wristwatches. The impact of the First World War of 1914–1918 dramatically shifted public perceptions on the propriety of the man's wristwatch and opened up a mass market in the postwar era. The creeping barrage artillery tactic, developed during the war, required precise synchronization between the artillery gunners and the infantry advancing behind the barrage. Service watches produced during

1287-447: A luxury brand using precious metals and jewelry, and in 1979, Alba, a low-priced brand for young people. In 1985, Orient and Seiko established a joint factory. In 1986, Baselworld allowed non-European manufacturers to participate, and Seiko began exhibiting that year. In 1988, Seiko invented the world's first wristwatch with an innovative mechanism called "Auto Quartz", in which a rotating oscillating weight rotates in response to

1404-487: A manner analogous to the pendulum of a pendulum clock . The tourbillon , an optional part for mechanical movements, is a rotating frame for the escapement, used to cancel out or reduce gravitational bias. Due to the complexity of designing a tourbillon, they are expensive, and typically found in prestigious watches. The pin-lever escapement (called the Roskopf movement after its inventor, Georges Frederic Roskopf ), which

1521-668: A mechanical movement. After a consolidation of the mechanical watch industry in Switzerland during the 1970s, mass production of quartz wristwatches took off under the leadership of the Swatch Group of companies, a Swiss conglomerate with vertical control of the production of Swiss watches and related products. For quartz wristwatches, subsidiaries of Swatch manufacture watch batteries ( Renata ), oscillators ( Oscilloquartz , now Micro Crystal AG) and integrated circuits (Ebauches Electronic SA, renamed EM Microelectronic-Marin ). The launch of

1638-568: A million units, symbolizing Seiko's partnership with the world's no.1 professional tennis player. Seiko – often criticised for quality standards that let misaligned chapter rings and bezels slip through – decided to move its brand positioning upmarket; in 2015, the Financial Times reported the Spring Drive movement’s enthusiastic reception prompted Seiko's launch of higher-end pieces. Harvard Business School reported: "In 2003, Shinji Hattori,

1755-455: A pocket watch. Cartier still markets a line of Santos-Dumont watches and sunglasses. In 1905, Hans Wilsdorf moved to London, and set up his own business, Wilsdorf & Davis, with his brother-in-law Alfred Davis, providing quality timepieces at affordable prices; the company became Rolex in 1915. Wilsdorf was an early convert to the wristwatch, and contracted the Swiss firm Aegler to produce

1872-682: A replaceable battery . The first use of electrical power in watches was as a substitute for the mainspring, to remove the need for winding. The first electrically powered watch, the Hamilton Electric 500, was released in 1957 by the Hamilton Watch Company of Lancaster, Pennsylvania . Watch batteries (strictly speaking cells, as a battery is composed of multiple cells) are specially designed for their purpose. They are very small and provide tiny amounts of power continuously for very long periods (several years or more). In most cases, replacing

1989-614: A reset of the timer. The original chronographs that Rieussec invented were called tape chronographs. They consisted of a tape that was constantly being dragged along at a controlled speed. When activated, a pen would be pushed onto the tape and begin recording until deactivated. Specialized chronographs are used by deep sea and scuba divers. While basic functionality is the same as other chronographs, diving models have longer and more practical straps to wear over equipment, are made to be waterproof to deeper depths, have more rounded corners to prevent catching and luminous dials for reading in

2106-541: A revolution time of sixty minutes. The three train wheels interact with one another and record how long it has been since the start button has been activated. In addition to the start button, it also features a reset button normally located at the four o'clock position. When the reset button is pushed the chronograph hand will reset back to zero. Tachymeter bezels are a complication that allows rapid calculations of speed or distance. Rotating bezels allow for more complex calculations or repeated calculations without requiring

2223-453: A rhythm of 216,000 vibrations per hour (30 Hz). This frequency record stood for exactly one century, before eventually being broken in 1916, after which standard chronometer frequencies returned to present-day levels (generally 5-10 Hz, or 18,000 to 36,000 vibrations per hour). Still in perfect working order, the Compteur de Tierces is preserved at Ateliers Louis Moinet. In 1913, Longines created

2340-534: A self-winding system as a separate module that could be used with almost any 8.75 ligne (19.74 millimeter) watch movement. Glycine incorporated this module into its watches in October 1930, and began mass-producing automatic watches. The Elgin National Watch Company and the Hamilton Watch Company pioneered the first electric watch . The first electric movements used a battery as a power source to oscillate

2457-466: A small pen attached to the index so that the length of the pen mark would indicate how much time had elapsed. The first modern chronograph was invented by Louis Moinet in 1816, solely for working with astronomical equipment. It was Nicolas Mathieu Rieussec who developed the first marketed chronograph at the behest of King Louis XVIII in 1821. The King greatly enjoyed watching horse races, but wanted to know exactly how long each race lasted, so Rieussec

2574-400: A specific highly stable frequency, which is used to accurately pace a timekeeping mechanism. Most quartz movements are primarily electronic but are geared to drive mechanical hands on the face of the watch to provide a traditional analog display of the time, a feature most consumers still prefer. In 1959 Seiko placed an order with Epson (a subsidiary company of Seiko and the 'brain' behind

2691-406: A start button, normally located at the two o'clock position, to begin recording time, and by pushing the same button to stop the recording. When the button is pushed to start the recording, a series of three (in more complicated and more precise chronographs there are more wheels) train wheels start turning. The smallest has a revolution time of one second, the next sixty seconds, and the final one has

2808-462: A titanium case. In 1978, Seiko introduced the world's first quartz diver's watch with a water resistance of 600 meters; in 1982, the world's first wristwatch with a television; in 1983, the world's first wristwatch with a record-and-play function and an analog quartz chronograph; in 1984, the world's first wristwatch computer; and in 1986, the world's first diver's watch with a ceramic case water-resistant to 1000 meters. In 1974, Seiko launched Credor,

2925-639: A tourbillion in a chronograph will differ from a tourbillion in a more simple timepiece. Other types of modern-day chronographs are the automatic chronograph and the digital chronograph . The automatic chronograph depends solely on kinetic energy as its power source, while the digital chronograph is much like the common stopwatch and uses a battery to gain power, as well as quartz for timing. Other, more specific, types of chronographs include split second chronographs, tide chronographs, and asthmometer chronographs. Each of these chronographs has an added feature that sets them apart. The telemeter chronograph allows

3042-617: A watch and jewelry shop called "K. Hattori" ([服部時計店] Error: {{Lang}}: invalid parameter: |labels= ( help ) ) in Tokyo. Kintarō Hattori had been working as clockmaker apprentice since the age of 13, with multiple stints in different watch shops, such as “Kobayashi Clock Shop”, run by an expert technician named Seijiro Sakurai; “Kameda Clock Shop” in Nihonbashi; and “Sakata Clock Shop” in Ueno, where he learned how to both sell and repair timepieces. Around

3159-431: A winding, requiring winding daily, some run for several days; a few have 192-hour mainsprings, requiring once-weekly winding. A self-winding or automatic watch is one that rewinds the mainspring of a mechanical movement by the natural motions of the wearer's body. The first self-winding mechanism was invented for pocket watches in 1770 by Abraham-Louis Perrelet, but the first " self-winding ", or "automatic", wristwatch

3276-400: A wrist. They generally incorporate timekeeping functions, but these are only a small subset of the smartwatch's facilities. In general, modern watches often display the day, date, month, and year. For mechanical watches, various extra features called " complications ", such as moon-phase displays and the different types of tourbillon , are sometimes included. Most electronic quartz watches, on

3393-402: A wristwatch, described as an "armed watch", from Robert Dudley . The oldest surviving wristwatch (then described as a "bracelet watch") is one made in 1806, and given to Joséphine de Beauharnais . From the beginning, wristwatches were almost exclusively worn by women – men used pocket watches up until the early 20th century. In 1810, the watch-maker Abraham-Louis Breguet made a wristwatch for

3510-447: Is a Japanese maker of watches, clocks, electronic devices, semiconductors , jewelry, and optical products . Founded in 1881 by Kintarō Hattori in Tokyo , Seiko introduced the world's first commercial quartz wristwatch in 1969. Seiko is widely known for its wristwatches. Seiko, Citizen and Rolex are the only three watch companies considered to be vertically integrated . Seiko

3627-440: Is a cheaper version of the fully levered movement, was manufactured in huge quantities by many Swiss manufacturers, as well as by Timex , until it was replaced by quartz movements. Introduced by Bulova in 1960, tuning-fork watches use a type of electromechanical movement with a precise frequency (most often 360 Hz ) to drive a mechanical watch. The task of converting electronically pulsed fork vibration into rotary movements

3744-419: Is a fusion between a regular mechanical watch and a smartwatch. The movement and case are the basic parts of a watch. A watch band or bracelet is added to form a wristwatch; alternatively, a watch chain is added to form a pocket watch. The case is the outer covering of the watch. The case back is the back portion of the watch's case. Accessing the movement (such as during battery replacement) depends on

3861-410: Is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist , attached by a watch strap or other type of bracelet , including metal bands, leather straps, or any other kind of bracelet. A pocket watch is designed for a person to carry in

3978-573: Is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko's mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts in-house. The company was incorporated (K. Hattori & Co., Ltd.) in 1917 and renamed Hattori Seiko Co., Ltd. in 1983 and Seiko Corporation in 1990. After reconstructing and creating its operating subsidiaries (such as Seiko Watch Corporation and Seiko Clock Inc.), it became

4095-617: Is claimed to be accurate to +/− 10 seconds a year and has a smooth sweeping second hand rather than one that jumps each second. Radio time signal watches are a type of electronic quartz watch that synchronizes ( time transfers ) its time with an external time source such as in atomic clocks , time signals from GPS navigation satellites, the German DCF77 signal in Europe, WWVB in the US, and others. Movements of this type may, among others, synchronize

4212-474: Is done via two tiny jeweled fingers, called pawls. Tuning-fork watches were rendered obsolete when electronic quartz watches were developed. Traditional mechanical watch movements use a spiral spring called a mainspring as its power source that must be rewound periodically by the user by turning the watch crown. Antique pocket watches were wound by inserting a key into the back of the watch and turning it. While most modern watches are designed to run 40 hours on

4329-436: Is for Tachymeter readings: a simple scale that allows rapid calculations of speed. Other bezels feature Telemeter scale, for distance. The watchmaking company Breitling offers a model with a rotating bezel, in conjunction with another, fixed, meter on the dial, scaled for use as a slide rule for more complex calculations. Flyback chronographs have a timing hand that can be rapidly reset, or flyback , to zero. Ordinarily

4446-618: The Observatory of Neuchâtel in 1967. In 1970, 18 manufacturers exhibited production versions of the beta 21 wristwatch, including the Omega Electroquartz as well as Patek Philippe , Rolex Oysterquartz and Piaget . The first quartz watch to enter production was the Seiko 35 SQ Astron , which hit the shelves on 25 December 1969, swiftly followed by the Swiss Beta 21, and then a year later

4563-865: The most expensive watch ever sold at auction was the Patek Philippe Henry Graves Supercomplication , the world's most complicated mechanical watch until 1989, fetching US$ 24 million ( CHF 23,237,000) in Geneva on 11 November 2014. As of December 2019, the most expensive watch ever sold at auction (and wristwatch) was the Patek Philippe Grandmaster Chime Ref. 6300A-010, fetching US$ 31.19 million (CHF 31,000,000) in Geneva on 9 November 2019. Watches evolved from portable spring-driven clocks, which first appeared in 15th-century Europe. The first timepieces to be worn, made in

4680-643: The quartz watch in 1969 in the form of the Seiko Astron 35SQ , and in 1970 in the form of the Omega Beta 21 was a revolutionary improvement in watch technology. In place of a balance wheel, which oscillated at perhaps 5 or 6 beats per second, these devices used a quartz-crystal resonator , which vibrated at 8,192 Hz, driven by a battery-powered oscillator circuit . Most quartz-watch oscillators now operate at 32,768 Hz, though quartz movements have been designed with frequencies as high as 262 kHz. Since

4797-443: The 13.33Z, one of the first chronograph movements ever developed for a wristwatch, featuring 18 jewels, a diameter of 29 mm and height of 6 mm, and a beat rate of 18,000 vph. It utilized a crown that was used both for winding the watch and serving as a pusher for the chronograph. In 1915, Gaston Breitling produced the first chronograph with a central seconds hand and a 30-minute counter. Later, in 1923, Gaston Breitling introduced

4914-491: The 16th century beginning in the German cities of Nuremberg and Augsburg , were transitional in size between clocks and watches. Nuremberg clockmaker Peter Henlein (or Henle or Hele) (1485–1542) is often credited as the inventor of the watch. However, other German clockmakers were creating miniature timepieces during this period, and there is no evidence Henlein was the first. Watches were not widely worn in pockets until

5031-462: The 17th century. One account suggests that the word "watch" came from the Old English word woecce – which meant "watchman" – because town watchmen used the technology to keep track of their shifts at work. Another says that the term came from 17th-century sailors, who used the new mechanisms to time the length of their shipboard watches (duty shifts). A rise in accuracy occurred in 1657 with

5148-462: The 1980s, more quartz watches than mechanical ones have been marketed. The Timex Datalink wristwatch was introduced in 1994. The early Timex Datalink Smartwatches realized a wireless data transfer mode to receive data from a PC. Since then, many companies have released their own iterations of a smartwatch, such as the Apple Watch , Samsung Galaxy Watch , and Huawei Watch . A hybrid smartwatch

5265-672: The CEH research laboratory in Neuchâtel , Switzerland. From 1965 through 1967 pioneering development work was done on a miniaturized 8192 Hz quartz oscillator, a thermo-compensation module, and an in-house-made, dedicated integrated circuit (unlike the hybrid circuits used in the later Seiko Astron wristwatch). As a result, the BETA 1 prototype set new timekeeping performance records at the International Chronometric Competition held at

5382-498: The Pacific meant the country could not rely on importing foreign timepieces. In 1951, Seiko broadcast its first radio commercial in Japan, and when Japan's first commercial television station opened in 1953, it broadcast Japan's first television commercial. The first Japanese commercial was supposed to be broadcast as a time signal at noon, but the video technician mishandled the equipment and

5499-528: The Queen of Naples. The first Swiss wristwatch was made in the year 1868 by the Swiss watch-maker Patek Philippe for Countess Koscowicz of Hungary. Wristwatches were first worn by military men towards the end of the 19th century, having increasingly recognized the importance of synchronizing maneuvers during war without potentially revealing plans to the enemy through signaling. The Garstin Company of London patented

5616-562: The Seiko pocket watch was adopted as the official watch for the drivers of Japanese Government Railways . Military watches produced for Japanese troops during World War II were manufactured by Seiko, which by 1938, produced 1.2 million timepieces a year. The scarcity of raw materials during the war diverted much of Seiko's production to on-board instruments for military aircraft and ships. In contrast to Japan, Germany utilized both domestically produced and Swiss-produced watches. Japan's isolation in

5733-412: The U.T.D., a mechanical wristwatch with a thickness of 1.98 mm. Since the 1970s, Seiko has introduced a variety of wristwatches with various world firsts: in 1973, Seiko introduced the world's first wristwatch with a LCD display capable of displaying six digits for hours, minutes and seconds; in 1975, Seiko introduced the world's first digital watch with a stopwatch function and a diver's watch with

5850-547: The United States. In 2006, Seiko launched the world's first wristwatch based on microcapsule E-ink technology. This watch was the first Seiko watch to win an award at the Grand Prix de Genève for its innovative ability to bend the display part, in addition to providing more contrast and a wider viewing angle than conventional LCD displays. In 2010, Seiko launched the world's first solar radio-controlled digital watch based on

5967-676: The United States. The models available in the United States are typically a smaller subset of the full line produced in Japan. Seiko Corporation of America is headquartered in Mahwah, New Jersey , alongside the Coserv repair center. In the United States, Seiko watches are sold primarily by fine jewelers, department stores, and 19 Seiko company stores. Seiko produces watches with quartz , kinetic , solar , and mechanical movements of varying prices, ranging from around ¥4,000 (US$ 45) to ¥50,000,000 (US$ 554,000). Seiko has created many different brands in Japan and

6084-462: The accuracy achieved by even the cheapest modern quartz watch). A simple mechanical watch, without the stopwatch functionality, can be certified a chronometer, as can a clock, for example a ship's clock, used for navigation. The terms are not mutually exclusive either, for instance the Omega Seamaster 300M Chronograph GMT Co-Axial is also a COSC certified chronometer Originally the term chronograph

6201-539: The active matrix EPD system, advancing the expression of information in digital watches. In 2012, Seiko launched the world's first GPS solar watch, the Seiko Astron GPS Solar. Seiko positioned this watch as the second revolutionary wristwatch after the Astron, which was launched in 1969, and described that it had the ultimate practical functionality, being able to instantly display extremely accurate time anywhere in

6318-542: The addition of the balance spring to the balance wheel, an invention disputed both at the time and ever since between Robert Hooke and Christiaan Huygens . This innovation increased watches' accuracy enormously, reducing error from perhaps several hours per day to perhaps 10 minutes per day, resulting in the addition of the minute hand to the face from around 1680 in Britain and around 1700 in France. The increased accuracy of

6435-657: The application of duplicating tools and machinery in 1843. In the United States , Aaron Lufkin Dennison started a factory in 1851 in Massachusetts that used interchangeable parts , and by 1861 a successful enterprise operated, incorporated as the Waltham Watch Company . The concept of the wristwatch goes back to the production of the very earliest watches in the 16th century. In 1571, Elizabeth I of England received

6552-454: The arm or wrist of the wearer creates kinetic energy , which results in the total energy source needed for this device to work. Throughout the day, while the wearer of the watch is walking, the swinging motion of his arm forces a semicircular rotor to turn on a pivot within the watch. The rotor is attached to a ratchet that winds the mainspring in the watch, so that it is ready for use at all times. The modern day chronograph works by pushing

6669-510: The aviation industry in the early part of the 20th century. As the US exploration of outer space initially involved only test pilots, by order of President Dwight D. Eisenhower , chronographs were on the wrists of many early astronauts. Chronograph usage followed a similar trajectory for many fields that involve very precise and/or repeated timing around increasingly more complicated high performance machinery, automobile racing and naval submarine navigation being two examples. As different uses for

6786-490: The balance assembly delivered the power to the balance wheel. Similar designs from many other watch companies followed. Another type of electric watch was developed by the Bulova company that used a tuning-fork resonator instead of a traditional balance wheel to increase timekeeping accuracy, moving from a typical 2.5–4 Hz with a traditional balance wheel to 360 Hz with the tuning-fork design. The commercial introduction of

6903-525: The balance wheel and the escapement for accuracy by laser . The low parts count and the fully automated assembly make it an inexpensive automatic Swiss watch. Electronic movements, also known as quartz movements, have few or no moving parts, except a quartz crystal which is made to vibrate by the piezoelectric effect . A varying electric voltage is applied to the crystal, which responds by changing its shape so, in combination with some electronic components, it functions as an oscillator . It resonates at

7020-409: The balance wheel focused attention on errors caused by other parts of the movement , igniting a two-century wave of watchmaking innovation. The first thing to be improved was the escapement . The verge escapement was replaced in quality watches by the cylinder escapement , invented by Thomas Tompion in 1695 and further developed by George Graham in the 1720s. Improvements in manufacturing – such as

7137-477: The balance wheel. During the 1950s, Elgin developed the model 725, while Hamilton released two models: the first, the Hamilton 500, released on 3 January 1957, was produced into 1959. This model had problems with the contact wires misaligning, and the watches returned to Hamilton for alignment. The Hamilton 505, an improvement on the 500, proved more reliable: the contact wires were removed and a non-adjustable contact on

7254-414: The basic function of telling time, as they are watches, and of displaying elapsed time. Rieussec's chronograph was fairly simple. It was composed of two faces, a top and bottom face. The bottom face held a pool of ink, while the upper had a pen-like needle attached to it. When activated, the upper face pushed down on the lower face, while revolving around a central axis, which pulled the needle. This dragged

7371-420: The battery requires a trip to a watch-repair shop or watch dealer; this is especially true for watches that are water-resistant, as special tools and procedures are required for the watch to remain water-resistant after battery replacement. Silver-oxide and lithium batteries are popular today; mercury batteries, formerly quite common, are no longer used, for environmental reasons. Cheap batteries may be alkaline, of

7488-799: The chronograph include the Langley Chronograph, which is used by the US Navy to record, calculate, and analyse data given off by aeroplane launching catapults. Another famous usage of the chronograph was during NASA's Apollo missions to the moon, when each astronaut was equipped with a fully functioning chronograph, the Omega Speedmaster ; in one instance, a Bulova chronograph was used. Chronographs are routinely used to record heart beats within hospitals, calculate speed and/or distance on athletic fields, or even as simple timers in kitchens. Chronographs can be extremely complicated devices, but they all have

7605-413: The chronograph were discovered, the industry responded with different models introducing such features as the flyback (where the second hand could be rapidly reset to zero), minute and hour timers, Rattrapante (or multiple second hands one of which can be stopped and started independently) and waterproof models for divers and swimmers. Although self winding watches and clockwork have been around since

7722-561: The commercial lasted only three seconds, and it was rebroadcast at 7:00 p.m. the same day. In 1956, Seiko launched Japan's first automatic wristwatch , the Automatic. The retail price at the time was 13,500 yen, more than three times the price of men's wristwatches, which were generally in the 4,000 yen range. In the same year, the company released the Marvel, which represented a significant improvement in accuracy, quality, and productivity over

7839-474: The competition, there were special movements for the competition. In 1969, Seiko launched the Astron , the world's first commercial quartz wristwatch ; when it was introduced, it cost the same as a medium-sized car. Seiko later went on to introduce the first quartz chronograph. The year 1969 marked the launch of the Astron, as well as several other wristwatches that Seiko positioned as its own historical models. In

7956-475: The constantly moving needle in the original chronograph. In the early part of the 20th century, many chronographs were sold with fixed bezels marked in order to function as a tachymeter . In 1958 the watch company Heuer introduced a model with a rotating bezel tachymeter for more complex calculations. Chronographs were very popular with aviators as they allowed them to make rapid calculations and conduct precise timing. The demand for chronographs grew along with

8073-654: The decades progressed and the efficiency of the solar cells increased while the power requirements of the movement and display decreased, solar watches began to be designed to look like other conventional watches. A rarely used power source is the temperature difference between the wearer's arm and the surrounding environment (as applied in the Citizen Eco-Drive Thermo). Seiko Seiko Group Corporation ( セイコーグループ株式会社 , Seikō Gurūpu kabushiki gaisha ) , commonly known as Seiko ( / ˈ s eɪ k oʊ / SAY -koh , Japanese: [seːkoː] ),

8190-428: The first chronograph with a separate pusher at 2 o'clock. In 1934 Willy Breitling further developed the concept of the chronograph with the addition of the second pusher at 4 o'clock. Since then the 3-pusher chronograph design has been adopted by the entire industry. In 1844 Adolphe Nicole's updated version of the chronograph was the first to include a re-setting feature which now allowed successive measurements, unlike

8307-524: The general public. In 1960, Seiko released the Grand Seiko, aimed to be the most accurate wristwatch in the world. Seiko quickly developed quartz technology in preparation for the 1964 Tokyo Olympics , and in 1963 launched the Seiko Crystal Chronometer, a dramatically smaller version of its previous quartz clock. The quartz clock Seiko had supplied to a broadcasting station in 1959 was about

8424-405: The ink, in a circular fashion, recording the time elapsed by the line of ink that the motion created. There was room left for improvement, because Rieussec's chronograph was not easily ready for multiple uses. This paved the way for the hundreds of patents that have been handed out to people for updating and upgrading this device. Automatic, non-digital chronographs do not require a battery, because

8541-479: The international market including Lorus, Pulsar , and Alba . Seiko has several lines such as the Seiko 5, luxury "Credor," "Prospex," "Presage," "Velatura", "Astron" and the " Grand Seiko " series. Seiko 5 is a sub brand that spawned with the introduction of the Seiko Sportsmatic 5 in 1963. Since then, many models have been introduced into the lineup, comprising a variety of different styles. The name of

8658-489: The key members of the Hattori family (posterity of Kintarō Hattori), the three companies in the group were not affiliated; they were managed and operated independently. On January 26, 2009, Seiko Holdings and Seiko Instruments announced the two companies would merge on October 1, 2009, through a share swap. Seiko Instruments became a wholly owned subsidiary of Seiko Holdings as of 1 October 2009. On October 1, 2022, Seiko Holdings

8775-437: The late 1700s, the automatic (self winding) chronograph was not invented until the late 1960s. In 1969, the watch companies Heuer, Breitling, Hamilton , and movement specialist Dubois Dépraz, developed the first automatic chronograph in partnership. They developed this technology secretly in an effort to prevent other watchmaking houses from releasing an automatic chronograph first, namely their competition Zenith and Seiko . It

8892-405: The mechanism for aesthetic purposes. A mechanical movement uses an escapement mechanism to control and limit the unwinding and winding parts of a spring, converting what would otherwise be a simple unwinding into a controlled and periodic energy release. The movement also uses a balance wheel , together with the balance spring (also known as a hairspring), to control the gear system's motion in

9009-423: The murky depths. Metered bezels: Many chronographs have a bezel, that is either fixed or can rotate, around the outside of the dial that is marked to specific scales to allow rapid calculations. While any wristwatch can have a bezel, the chronograph stop start feature, as well as the rotation of the bezel, allows more complex calculations or repeated measurements for a series of calculations. The most popular meter

9126-474: The name Seikosha ( 精工 舎 , Seikōsha ) , meaning, roughly, "House of Exquisite Workmanship." According to Seiko's official company history, titled A Journey In Time: The Remarkable Story of Seiko (2003), Seiko is a Japanese word meaning "exquisite" ( 精巧 , Seikō ) ; it is homophonous with the word for "success" ( 成功 , Seikō ) . In 1895, the watch dealer purchased the corner of Ginza 4-chome (the present-day location of WAKO ), and constructed

9243-651: The new SWATCH brand in 1983 was marked by bold new styling, design, and marketing. Today, the Swatch Group maintains its position as the world's largest watch company. Seiko 's efforts to combine the quartz and mechanical movements bore fruit after 20 years of research, leading to the introduction of the Seiko Spring Drive , first in a limited domestic market production in 1999 and to the world in September 2005. The Spring Drive keeps time within quartz standards without

9360-718: The other hand, include time-related features such as timers , chronographs , and alarm functions. Furthermore, some modern watches (like smart watches) even incorporate calculators , GPS and Bluetooth technology or have heart-rate monitoring capabilities, and some of them use radio clock technology to regularly correct the time. Most watches that are used mainly for timekeeping have quartz movements. However, expensive collectible watches, valued more for their elaborate craftsmanship, aesthetic appeal, and glamorous design than for simple timekeeping, often have traditional mechanical movements, despite being less accurate and more expensive than their electronic counterparts. As of 2018,

9477-418: The other was Suwa Seikosha Co. (now known as Seiko Epson Corporation, an independent publicly traded company). Having two companies both producing the same brand of watch enabled Seiko to improve technology through competition and hedge risk . It also reduced risk of production problems, since one company can increase production in the case of decreased production in the other parties. Seiko remains as one of

9594-539: The previous model. This was achieved by increasing the outer diameter of the movement compared to the previous model. In 1958, Seiko developed the 'Dia-Shock' anti-shock device. In 1959, Seiko launched the Gyro Marvel, which featured a revolutionary self-winding mechanism, the Magic Lever, developed by Seiko. The Magic Lever was simple in structure and had high winding performance, and popularized automatic watches among

9711-469: The prototype of one of the world's most accurate wristwatches to date: the Omega Marine Chronometer . Since the technology having been developed by contributions from Japanese, American and Swiss, nobody could patent the whole movement of the quartz wristwatch, thus allowing other manufacturers to participate in the rapid growth and development of the quartz watch market. This ended – in less than

9828-481: The quartz revolution) to start developing a quartz wristwatch. The project was codenamed 59A. By the 1964 Tokyo Summer Olympics , Seiko had a working prototype of a portable quartz watch which was used as the time measurements throughout the event. The first prototypes of an electronic quartz wristwatch (not just portable quartz watches as the Seiko timekeeping devices at the Tokyo Olympics in 1964) were made by

9945-569: The rarity of the imported watches the shop was selling, which couldn't be found anywhere else in Japan. The growing success allowed him to relocate the company to the main street of Ginza (Tokyo), still the epicenter of commerce in Japan to this day. In 1891, 10 years after the establishment of K. Hattori & Co., the 31-year-old Kintaro was appointed director of the Tokyo Clockmaker and Watchmaker Association and member of Tokyo Chamber of Commerce. In 1892, Hattori began to produce clocks under

10062-561: The rechargeable battery or capacitor. As long as the watch is regularly exposed to fairly strong light (such as sunlight), it never needs a battery replacement. Some models need only a few minutes of sunlight to provide weeks of energy (as in the Citizen Eco-Drive ). Some of the early solar watches of the 1970s had innovative and unique designs to accommodate the array of solar cells needed to power them (Synchronar, Nepro, Sicura, and some models by Cristalonic, Alba , Seiko, and Citizen). As

10179-405: The same size as silver-oxide cells but providing shorter life. Rechargeable batteries are used in some solar-powered watches . Some electronic watches are powered by the movement of the wearer. For instance, Seiko's kinetic-powered quartz watches use the motion of the wearer's arm: turning a rotating weight which causes a tiny generator to supply power to charge a rechargeable battery that runs

10296-479: The same year, Seiko introduced the Five Sport Speed Timer, the world's first Magic Lever watch with a vertical clutch and column wheel. It was a resounding success for its compactness and practicality, and had a major influence on subsequent chronographs around the world. The company also launched the Grand Seiko V.F.A., a mechanical wristwatch with ultra-high accuracy of plus or minus two seconds per day, and

10413-399: The second hands travel together, one under the other, to appear as just one second hand. A tourbillon , although not strictly limited to chronographs, is an escapement set in a cage and placed in a rotating balance in order to minimize the effects of gravity on the escapement and increase precision. Because chronograph escapements are generally larger and connect with more complications,

10530-492: The single most important technological breakthrough, though invented by Thomas Mudge in 1754 and improved by Josiah Emery in 1785, only gradually came into use from about 1800 onwards, chiefly in Britain. The British predominated in watch manufacture for much of the 17th and 18th centuries, but maintained a system of production that was geared towards high-quality products for the élite. The British Watch Company modernized clock manufacture with mass-production techniques and

10647-525: The size of a wardrobe, but this new product ran on two batteries and was portable. At the Tokyo Olympics, Seiko's mechanical stopwatches were selected as the official Olympic watches due to their high accuracy. Seiko launched Japan's first chronograph wristwatch, the Crown Chronograph, in 1964, Japan's first world time wristwatch in the same year, and Japan's first diver's wristwatch in 1965. In 1967, Japan's first diver's watch with 300m water resistance

10764-461: The sweep second hand is stopped to record the time and started again at that spot on the dial, or reset by spinning the second hand all the way to zero again, clockwise. The flyback allows a reading and a quick reset—a counterclockwise flyback—for the next measurement to start at zero. A rattrapante , sometimes called a double chronograph , has multiple second hands, at least one of which can be stopped and started independently. When not activated,

10881-488: The term chronometer . Where "Chronograph" refers to the function of a watch, chronometer is a measure of how well a given mechanical timepiece performs: in order to be labeled a chronometer the timepiece must be certified by the COSC , the official Swiss Chronometer testing institute, after undergoing a series of rigorous tests for robustness, accuracy and precision under adverse conditions (though these requirements fall far short of

10998-468: The time of Seiko's founding, watchmakers in Tokyo, Osaka , and Nagoya were studying and producing pocket watches based on Western products. Japanese wholesalers needed to purchase all the imported timepieces from foreign trading companies established in Yokohama, Kobe, and other open port areas. In 1885, Hattori began dealing directly with these foreign trading firms in the Yokohama settlement focused on

11115-406: The time of day and the date, the leap-year status and the state of daylight saving time (on or off). However, other than the radio receiver, these watches are normal quartz watches in all other aspects. Electronic watches require electricity as a power source, and some mechanical movements and hybrid electronic-mechanical movements also require electricity. Usually, the electricity is provided by

11232-515: The tooth-cutting machine devised by Robert Hooke – allowed some increase in the volume of watch production, although finishing and assembling was still done by hand until well into the 19th century. A major cause of error in balance-wheel timepieces, caused by changes in elasticity of the balance spring from temperature changes, was solved by the bimetallic temperature-compensated balance wheel invented in 1765 by Pierre Le Roy and improved by Thomas Earnshaw (1749–1829). The lever escapement ,

11349-416: The type of case back, which are generally categorized into four types: The crystal, also called the window or watch glass, is the transparent part of the case that allows viewing the hands and the dial of the movement. Modern wristwatches almost always use one of 4 materials: The bezel is the ring holding the crystal in place. The lugs are small metal projections at both ends of the wristwatch case where

11466-481: The use of a battery, using a traditional mechanical gear train powered by a spring, without the need for a balance wheel either. In 2010, Miyota ( Citizen Watch ) of Japan introduced a newly developed movement that uses a 3-pronged quartz crystal that was exclusively produced for Bulova to be used in the Precisionist or Accutron II line, a new type of quartz watch with ultra-high frequency (262.144 kHz) which

11583-622: The use of wristwatches subsequently became widespread among the officer class. The company Mappin & Webb began production of their successful "campaign watch" for soldiers during the campaign in the Sudan in 1898 and accelerated production for the Second Boer War of 1899–1902 a few years later. In continental Europe, Girard-Perregaux and other Swiss watchmakers began supplying German naval officers with wristwatches in about 1880. Early models were essentially standard pocket-watches fitted to

11700-540: The user to approximately measure the distance to an event that can be both seen and heard (e.g. a lightning bolt or a torpedo strike) using the speed of sound. The user starts the chronograph (stopwatch) at the instant the event is seen, and stops timing at the instant the event is heard. The seconds hand will point to the distance measured on a scale, usually around the edge of the face. The scale can be defined in any unit of distance, but miles or kilometers are most practical and commonplace. Watch#Digital A watch

11817-472: The war were specially designed for the rigors of trench warfare , with luminous dials and unbreakable glass. The UK War Office began issuing wristwatches to combatants from 1917. By the end of the war, almost all enlisted men wore a wristwatch (or wristlet ), and after they were demobilized, the fashion soon caught on: the British Horological Journal wrote in 1917, that "the wristlet watch

11934-412: The watch band attaches to the watch case. The case and the lugs are often machined from one solid piece of stainless steel. The movement of a watch is the mechanism that measures the passage of time and displays the current time (and possibly other information including date, month, and day). Movements may be entirely mechanical, entirely electronic (potentially with no moving parts), or they might be

12051-402: The watch. The concept is similar to that of self-winding spring movements, except that electrical power is generated instead of mechanical spring tension. Solar powered watches are powered by light. A photovoltaic cell on the face ( dial ) of the watch converts light to electricity, which is used to charge a rechargeable battery or capacitor . The movement of the watch draws its power from

12168-413: The wearer's arm movements, generating electricity to power the quartz. This mechanism was developed with the aim of creating a quartz watch that does not require battery replacement. This mechanism was adopted as Seiko's core movement and later renamed "A.G.S.". (Automatic Generating System). In 1991, to increase popularity, the watches were relaunched under the name "Seiko Kinetic". In 1998, Grand Seiko

12285-449: The wearer's wrist motions are inadequate to keep the watch wound. In April 2013, the Swatch Group launched the sistem51 wristwatch. It has a mechanical movement consisting of only 51 parts, including 19 jewels and a novel self-winding mechanism with a transparent oscillating weight. Ten years after its introduction, it is still the only mechanical movement manufactured entirely on a fully automated assembly line, including adjustment of

12402-450: The wholesaling and retailing of western (imported) timepieces and machinery. Over the years, Hattori developed a close partnership with multiple foreign trading firms, including C&J Favre-Brandt, F. Perregaux & Co. , Zanuti & Cie. and Siber & Brennwald , allowing him to obtain exclusive imported timepieces and machinery, which was not available elsewhere at that time. Hattori's shop became increasingly popular due to

12519-498: The world and working as long as there is light. Seiko's low power consumption GPS receiver contributed to the practical application of this watch. K. Hattori & Co. (currently Seiko Group Corporation) was one of the three core companies of the former Seiko Group . Seiko Group consisted of K. Hattori (SEIKO), Daini Seikosha (currently Seiko Instruments Inc. , SII), and Suwa Seikosha (currently Seiko Epson Corporation , EPSON). Although they had some common shareholders, including

12636-596: The world's most recognised watchmaking brands. At present, quartz and Spring Drive watches are manufactured in Shiojiri, Nagano ( Epson ), and mechanical watches in Shizukuishi, Iwate (Morioka Seiko Instruments). Some of the watches exported abroad, such as the Seiko 5, are also manufactured in Ninohe, Iwate , by Ninohe Tokei Kogyo (established in 1974 as a parts factory for Seiko). In 1881, Seiko founder Kintarō Hattori opened

12753-474: Was commissioned to invent a contraption that would do the job: as a result he developed the first ever commercialized chronograph. Rieussec was considered the inventor of the chronograph until the Louis Moinet pocket chronograph discovery in 2013 when history was rewritten. In addition to inventing the chronograph, Louis Moinet is also the father of High Frequency. In 1816, his Compteur de Tierces timepiece beat at

12870-471: Was in Geneva and in New York that this partnership shared the first automatic chronograph with the world on March 3, 1969. These first automatic chronographs were labelled "Chrono-matic". Many companies sell their own styles of chronographs. While today most chronographs are in the form of wristwatches, in the early 20th century pocket chronographs were very popular. The term chronograph is often confused with

12987-476: Was invented, which was powered by a battery and kept time with a vibrating quartz crystal . By the 1980s the quartz watch had taken over most of the market from the mechanical watch. Historically, this is called the quartz revolution (also known as the quartz crisis in Switzerland ). Developments in the 2010s include smart watches , which are elaborate computer-like electronic devices designed to be worn on

13104-440: Was launched. In 1967, Seiko won second and third place in a watch accuracy competition at a Neuchâtel Observatory competition; the competition was canceled after that year. In 1968, Seiko took first place in a Geneva Observatory competition with a score of 58.19, surpassing all previous records. Swiss companies ranked first to third for their quartz movements and Seiko ranked fourth to tenth for its mechanical movements. In

13221-463: Was little used by the sterner sex before the war, but now is seen on the wrist of nearly every man in uniform and of many men in civilian attire." By 1930, the wristwatch vastly exceeded the pocket watch in market share by a decisive ratio of 50:1. John Harwood invented the first successful self-winding system in 1923. In anticipation of Harwood's patent for self-winding mechanisms expiry in 1930, Glycine founder Eugène Meylan started development on

13338-412: Was mainly used in connection with artillery and the velocity of missiles. The Chronograph's main function is to allow a comparison of observation between a time base and, before the electronic stopwatch was invented, a permanent recording of the observer's findings. For example, one of the first applications of the chronograph was to record the time elapsed during horse races. Some more important uses of

13455-587: Was released with the first new mechanical movement in 20 years. In 1999, Seiko launched Spring Drive , the world's first mechanical wristwatch with the accuracy of quartz. In 2004, the Astron, launched in 1969, was selected as an IEEE milestone. In the same year, Seiko began operating the Shizukuishi Watch Studio, which specializes in high-end watches. In 2005, Seiko launched the world's first solar-powered analog watch that adjusts its accuracy by receiving three radio signals from Japan, Germany, and

13572-528: Was renamed Seiko Group. Epson still develops and manufactures some of the Seiko's highest grade watches, but is managed and operated completely independently from Seiko Group. On January 10, 2014, on the eve of the Australian Open in Melbourne , Shinji Hattori, President of Seiko Watch Corporation, presented to Novak Djokovic a Seiko Astron GPS Solar limited edition worth $ 1700. It was launched worldwide with

13689-472: Was the invention of a British watch repairer named John Harwood in 1923. This type of watch winds itself without requiring any special action by the wearer. It uses an eccentric weight, called a winding rotor, which rotates with the movement of the wearer's wrist. The back-and-forth motion of the winding rotor couples to a ratchet to wind the mainspring automatically. Self-winding watches usually can also be wound manually to keep them running when not worn or if
