2014 JDM limited run and discontinued Seiko Brightz SDGM001 (Baby Grand Cocktail) I picked up recently from Japan. LNIB, still in factory stickers. The SDGM001 features the Seiko Comfotex technology which include special treatment to the case and crystal of the watch. The crystal is coated with “Super Clear Coating” on both sides to suppress reflection of light. In it's background a Grand-Seiko-esque dynamic dial, onyx decorated crown, and a blue seconds hands (The watch reminds me of GS SBGW297). In addition, it has an water-repellent applied to the coating to provide resistance to stains and scratches. For the case, Seiko applied it’s proprietary surface processing technology, Diashield to provide further resistance to scratch.

	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.
