SEIKO QUARTZ Chronograph SSB347 History
The company was founded in 1881, when Kintarō Hattori opened a watch and jewelry shop called “K. Hattori” (服部時計店 Hattori Tokeiten) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under 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” or “success” (“exquisite” is usually written 精巧 from Chinese jīngqiǎo, while the meaning “success” is usually written 成功 from Chinese chénggōng).
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 the late 1980s, Seiko produced the first automatic quartz that combined the self-energizing attributes of an automatic watch with quartz accuracy. The watch is entirely powered by its movement in everyday wear. In 1991, to increase popularity, these watches were relaunched under the name Seiko Kinetic.
