Selling my Seiko Marine Master 300 SBDX017. It has some surface swirls but no major dings or dents. The most notable mark is on the bezel insert around the 50 mark. It can be seen in the picture if you zoom in. On the wrist it looks great. The bracelet is in very good shape... it's was not worn much. The watch received a service and new crystal in from the Seiko service center in January. The famous 8L35 movement is running well as expected right after a service and the crystal is spotless. Comes with the box, warranty book, instruction book and hang tags. I'm also including a Crafter Blue Strap (black) with a Seiko Titanium deployant clasp and a rubber single pass nato with a Seiko keeper and Ti buckle. $1200 shipped to CONUS. Great price on a great watch.

	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.
