I purchased this watch ~5 months ago in this subreddit. It’s beautiful, especially in sunlight, but I just tend to wear my neutral colored watches much more. Only worn this a few times. Seiko Brightz Grand Cocktail SDGC030, a model limited to just 500 pieces, only sold once in this subreddit (to me) released in 2014. Rose gold plated, ruby/burgundy sunburst dial. decorated with ruby red crystals at the corner of each indice. Crown is decorated with red stone and caseback glass is red. powered by 28,800vph 6R21 mechanical movement featuring a PR indicator on the left, date subdial on the bottom, and day of the week subdial on the right. 40mm diameter. Crystal is clean, watch comes with warranty paper generic watch box and original buckle. Asking $1200 Paypal F&F or +4.4% G&S, I had several people message me trying to buy this watch right after I purchased it but I couldn’t let it go at the time. Willing to now.

	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.
