Seiko Watch company started in 1881, when Kintar Hattori opened a watch and jewelry shop in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seiko-sha . Seiko is a Japanese word meaning "exquisite," minute," "success." The first watches produced under the Seiko brand appeared in 1924. In 1969, Seiko introduced the Astron, the world's first production quartz watch; when it was introduced, it cost the same as a medium-sized car. Seiko later went on to introduce the first quartz chronograph. In 1985, Orient Watches and Seiko established a joint factory. Recognized as a leader in timekeeping accuracy, Seiko products are often used as the official timekeepers of the major sporting events, including the Olympic Games and the FIFA World Cup editions in Argentina 1978, Spain 1982, Mexico 1986, and Italy 1990. Seiko is perhaps known best, though, for its wristwatches. They are known for their advanced technology and are one of the few wristwatch manufacturers that produce all of their watches and movements entirely in-house. Even minor items such as the oils used in lubricating the watches and the luminous compounds used on the hands and the dials are produced by the Seiko factories. Seiko produces both quartz and mechanical watches of varying prices. Seiko's mechanical watches are the most prized by collectorsfrom the Seiko "5" series (the 5 reflects the five essential features of the watch, namely shock resistant, water resistant, automatic, and day and date display), which is the most common; the Seiko automatic Chronometer series; the "Bell-Matic," with a mechanical alarm; to the highly prized luxury "Credor," "King Seiko," and "Grand Seiko" lines. Seiko Kinetic Watches account for a large proportion of sales nowadays and combine the self-energizing attributes of an automatic watch with quartz accuracy. There is no battery to change; the watch is entirely powered by its movement in everyday wear. Seiko Corporation of America is responsible for distribution of Seiko watches, as well as Pulsar brand watches, in the United States. The models available in the United States are normally a smaller subset of the full line produced in Japan. However Wristzonewatches is proud to present many of the international models, Seiko Corporation of America has its headquarters (and Coserv repair center) in Mahwah, New Jersey. In the United States,
Seiko Spring Drive, a new movement that provides 72 hours of power, as opposed to the average of 40 hours in automatic mechanicals. This new movement, which employs a special alloy called "Spron510", has eliminated the traditional balance wheel/escapement regulating system in favor of a "Tri-synchro Regulator." The power from the spring is used to turn the wheels but is also used to generate electrical power for a tiny, ultra-low consumption (~25 nanowatts) crystal oscillator, which in turn is used to regulate (with quartz accuracy) the speed of the wheels to eight beats per second.
