Timestamp: [https://imgur.com/a/EjvzzI9](https://imgur.com/a/EjvzzI9) Up for sale is my gorgeous vintage Grand Seiko 44GS reference 4420-9000, known as the "Grammar of Design". This is a true classic when it comes to vintage Grand Seiko. This is a catch and release for me as I purchased from a reputable seller here on WatchEx, and am letting it go for only because it wears much smaller than I expected at 36.5mm. Link to the original post with way better pictures than I can take here: [https://www.reddit.com/r/Watchexchange/comments/1qefgdy/wts\_grand\_seiko\_44209000\_grammar\_of\_design\_44gs/](https://www.reddit.com/r/Watchexchange/comments/1qefgdy/wts_grand_seiko_44209000_grammar_of_design_44gs/) The watch is in honest vintage worn condition, with the case and crystal showing hairline scratches. Running great at 308 amplitude and + 5 seconds per day per timegrapher. Asking a firm $1350 shipped, which I'm pretty sure will be the cheapest listing of this reference you'll find online. Happy to meet in the Chicagoland area for face to face transactions.

	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.
