Seiko is a Japanese watch company. The company started in 1881. 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.
The all-time best selling Seiko watches for men are:
Dress Silver-Tone Watch SGF719J
Titanium Watch Seiko SGG709
Flight Alarm Chronograph Watch
Coutura Men's Kinetic Perpetual Watch SNP007
And the Chronograph Black Ion Watch SNA765
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.
The Spring Drive
On 7 October 2005, Seiko announced the world launch of the 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.
