This is the magnificent 300M diver from Seiko, SBDX017. Steel monocoque case, silky 120 click uni bezel, nuclear lume, superb 8L35 automatic movement ticking away at 28,800 bph, and the slick ratcheting fliplock clasp on the 5 piece steel bracelet. This version has an X on the crown, but the dial is inky black without it.

This particular beast has virtually no marks on the watch head at all, and only light desk diver marks on the clasp. No box or papers. Keeping excellent time vs NIST (~4 secs a day).

$1550 OBO shipped in USA.

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.
