Hello r/watchexchange, For sale today is my SAGM005, purchased earlier this year. The vitals: 8F32 HAQ perpetual calendar movement. You never have to set the date on this bad boy, including leap years. Titanium cushion case in a fantastic size: 38mm diameter, 45mm lug to lug, 11mm thick, 20mm lug width Titanium bracelet keeps it lightweight. Original clasp has been brushed. No spare links, but it will fit up to a 6.5” wrist. The original movement went kaput, so this has a donor 8F movement. Hence the white date wheel. Condition is otherwise quite good. Images: https://imgur.com/a/E60XH3Y Timestamp: https://i.imgur.com/1r89fQm.png This is a JDM mode so it’s somewhat unusual to see one for sale in CONUS. Avoid the tariffs and duties and such. I’m asking $675 shipped. I’m open to trades.

	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.
