This is an excellent example of an iconic watch. While not a true "Pogue" the blue model here exemplifies 1970s cool - at least to me!

I purchased this watch from Hub City Vintage this spring. Seals were replaced, crystal replaced, and the movement was fully serviced. It's running well and is quite accurate. Case surfaces are original. The case back has an engraving, but a pristine spare case back for the same model, from the same year, is also provided.

41mm diameter
19mm lugs
6139 movement - serviced
Brand new JDM-style 6139 bracelet from Uncle Seiko, full length

This is a great watch. I'm only selling because I purchased another, rarer, 6139.

Asking $650. Payment via PayPal, please. Includes shipping Priority Mail to the continental USA.

	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.
