Continuing to reduce my vintage Grand Seiko collection and up for sale is a nice no-date 45GS (4520-8000) which is one of the more desirable vintage Grand Seikos. This is a really nice all original honest example that has an unpolished and sharp case, original crystal, and excellent caseback. The dial has some light “tropical dial” aging that gives it a nice vintage look. Also on a really nice blue deployment strap. Running excellent, and I can get additional photos and a time graph photo later today. $1500 shipped, located in Houston.

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.
