I have the SBDC011 Field Tuna (watch and original strap, plus the awesome Strapcode Engineer bracelet pictured)for $850 shipped in USA. This features the 6R15 movement and has 200M water resistance. Becoming a bit rare these days and mine is in very good condition. I just don't wear it much in my collection anymore, so come and get it!
Thanks!

Price: $850.00

MediumRB is a great Seller!

Just received a Seiko from MediumRB and it’s been a real pleasant and smooth transaction. I would not hesitate to purchase again from him, that is, if my wallet permits. Thanks once again! Sent from my iPhone using Tapatalk

Mediumrb is a top seller

Hey all- Newbie here making my first purchase on Watchuseek after losing my beloved Blumo a few weeks ago. Bought a replacement from David in addition to another vintage Seiko diver, and he had them delivered to the US from Korea in 3 days. Very communicative and honest to deal …

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.
