Looking to sell my limited edition SBEX011 aka SLA039 MM300 Marinemaster Reissue with the Hi-Beat 8L55 which basically makes it a Grand Seiko. This is a super nice reissue with the clean blue/gray dial, everbrilliant steel, and Hi-Beat movement. Only reason I’m selling is it doesn’t get the wrist time it should and I’m on a Grand Seiko kick at the moment. Watch is in great condition with normal light scratches and no major dings. Only quirk with this example is the date change doesn’t “snap” for some of the dates between ~10-20. Most of them do “snap” properly and change/quickset all function properly, however that had been factored into asking price. Located in Houston - 2650$ shipped zelle, venmo, FF, or Wise for international. (PP G&S price is $2745 shipped)

	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.
