Up for sales is my SBGA429. I believe I am the second owner, it was purchased by me off ebay and went through the guarantee process. I have my eye on something else and I have a one-in one-out policy. This is 39mm. [https://www.grand-seiko.com/us-en/collections/sbga429g](https://www.grand-seiko.com/us-en/collections/sbga429g) It is in excellent condition with only one cosmetic issue; some marks just next to the crystal around 4/5 oclock. It came like this and am not sure how such marks get there. Running great and to spec. This comes with the box and only the leather; no metal bracelet. Asking price is $3900 Paypal F&F preferred but other options are possible.

	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.
