For Sale! Asking $1100. Seiko SBBN049 in excellent condition, with all original papers, all bracelet links and boxes included. This watch has been worn as a desk diver and has barely ever left my house. It is in excellent condition and only has very minor scratches on the clasp. The clasp has a diver’s extension built in. The crystal is internally-domed sapphire which gives the dial face a cool but still very-legible distortion from certain angles. The quartz movement keeps nearly perfect time and I’ve only noticed it to be several seconds off after over 6 months of use. The lume on this watch is amazingly bright. Please message me if you have any questions about the 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.
