# SBGA101 Video: [https://youtube.com/shorts/jGbZGrltVrQ?feature=share](https://youtube.com/shorts/jGbZGrltVrQ?feature=share) Up for sale is this excellent Japanese domestic market Grand Seiko Spring Drive model, reference SBGA101. This piece has the rare-to-Grand Seiko lumed dial and hands, and features a 40mm case that has slightly angled lugs with flat edges instead of a smooth line down to the end of the case. They reflect the light beautifully, and the angles and combination of brushed and polished surfaces subtly mirrors the hand and dial marker shape and finishing, pulling the watch together in a very pleasing way. The case measures 40mm wide, with a 48mm lug to lug length, 19mm lug width, and 13mm thickness. Wrist shot is of the watch on my \~6.75" wrist. It comes with the inner box and bracelet measuring 8" laid flat with the watch.

I am happy to do a video call to show the watch. I will ship internationally and only charge the difference in cost on top (Wise accepted for international payments). I’m not interested in trades. Feel free to reach out with any questions!

Great experience & transaction with mattmcmhn

Extremely flexible with my requests and questions. Adjusted the 2 day shipping to overnight with reasonable price adjustment. The watch I received "Tudor Black Bay" is absolutely as described and pictured with the box/papers. A 100% perfect transaction. Thanks again Matt! Adam

Smoothe transaction with Mattmcmhn!!

Just purchased a Pelagos from Mattmcmhn! Everything was better than stated. Matt immediately mailed the watch upon receipt of the funds. He answered all my questions and everything was better than I anticipated. I will purchase from Matt anytime!

mattmcmhn (Matt) is a soloid seller!

I just received a Rolex Explorer II from Matt, very smooth deal. The watch is better than advertised. I'd have no problem buying from him again. My only complaint, it was a tossup between my sawzall and the Jaws of Life to get the package opened, very securely packaged!!

	Established:	1881
	Website:	http://seikousa.com/index.php
	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.
