Discontinued Emperor Tuna with box and papers, 3 year warranty from May 1, 2025.
Picked this up at the beginning of the summer and just have not been able to wear it for more than a couple of minutes. No open water near me and certainly not 1000m depth rating needed. Pics are below and the watch is in excellent condition but not mint. Asking $3000 CAD, or equivalent, (today that is about 1600 gbp, 2200 usd, 3200 aid) shipped at cost almost anywhere fully insured. Buyer will be responsible for duties or taxes to import. Sending to USA is a PITA as noted in several threads on this forum, but it is possible…..

Please search my username for feedback, I have been on the forum for quite a while and bought and sold from many here, and I value my presence here, so please ask questions, and find out what you need so there are no surprises.

	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.
