For sale is my Seiko SBBN013 MarineMaster in excellent condition. It was serviced by Seiko in July 2023 and remains in outstanding shape. The only notable flaw is a faint mark around the 50-minute mark on the bezel. Additionally, the bezel is difficult to turn—a common issue with this model. Includes: Original box, owners guide, and battery change replacement coupon! Original strap (with hardware) Replacement OEM strap (with hardware) (brand new!) Two Uncle Seiko GL831 straps (one black, one green, both excellent condition and with black buckles) Price: $1,250, including shipping within CONUS, via PayPal.

	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.
