WatchEx, Bit off a bit more than I could chew to restore this Seiko 6105-8009 with j caseback and clean genuine 6105A movement. The dial, bezel, hands, crystal, crown, and strap are aftermarket. The case is in great shape and the movement runs and winds but does need a service. Sold as-is and can’t make any guarantees on accuracy. This model is one of the rarest of the 6105 divers. November 1970 serial. This is great for someone who wants to restore or mod further. It could be worn as is but please know what you’re getting. I purchased from a very reputable dealer on eBay but isn’t a good candidate for a first restoration project. Asking $550 conus and will cover shipping. Mostly looking for cash but will look at trades, ideally for a modern Willard. Thanks for looking.

	Established:	1881

	Country of Origin:	Japan

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.
