Up for sale is a Seiko 5 Ref. 6119-8100, circa 1968, another legendary MACV-SOG Seiko issued during the Vietnam War era. Like the 6619-8060, it runs when shaken, but I haven’t tested accuracy. This model was chrome-plated, and due to age, some parts of the case have peeled. Everything is original, except for the strap, which was purchased as NOS.

This isn’t a regular Seiko 5, so please do your research before reaching out. Prefer to sell as a pair with the 6619-8060, but willing to consider individual offers.

Ships within the U.S. only (buyer pays shipping, around $15).

Local meet-up available in Orange County.

Payment via Venmo, Zelle, or PayPal (Friends & Family).

I have buy/sell references if needed.

No returns, so please check everything carefully before purchasing. Ask as many questions as you need and request more photos if necessary.

I can also do face-to-face transaction in Orange County area.

Thank you OF for the space, greatly appreciate!

	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.
