**Seiko 6139-8002** Manufacture date: September 1971 Timestamp: [https://imgur.com/4N1pe0t](https://imgur.com/4N1pe0t) Album: [https://imgur.com/a/0DlTABC](https://imgur.com/a/0DlTABC) **Looks** Small blemish on the crystal just below the 1 marker. Have NOS crystals in stock if you wish to have it replaced, just pay for the crystal! Though I would say this is a pretty minor flaw. Expected aging of the dial and hands as well as signs of wear on the case. No major marks or anything else worth mentioning. New leather strap, never worn. **Functionality** Service history is unknown, can be serviced for an additional fee. Though watch is running well and keeping time. Chrono stop/start/reset functions are working. The reset function doesn't 'click' or snap back the hands, it's more of a smooth/linear movement. Hands reset to 12. **Price** $349 shipped and open to offers but no trades at this time.

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).

Seiko is perhaps best known for its wristwatches, all of which were at one time produced entirely in-house. This includes not only major items such as microgears, motors, hands, crystal oscillators, batteries, sensors, LCDs but also minor items such as the oils used in lubricating the watches and the luminous compounds used on the hands and the dials.
