Price: $1600 plus shipping USPS Priority Insured CONUS Payment: Zelle or bank wire, or PayPal/venmo FF for buyers with significant transaction history For sale, Seiko SLA053. In my opinion the most interesting Marinemaster. Sadly discontinued, this is an awesome, fully spec’d diving watch. This particular one is coated in black and topped with “super hard” coating. 44mm (wears like a 42), 50 lug to lug. Traditional Japanese art print onto the watch face. 8L35 movement. This watch is basically new. Purchased last month from Exquisite Timepieces. Hang tags still attached. No flaws whatsoever. Pip and ring line up perfectly. Watch works flawlessly. Great bezel action. Full kit, including box, receipt, hang tags, etc. Please examine photos carefully and ask questions. All sales are absolutely final. Happy to arrange a video call for visual inspection.

	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.
