Hey folks! As many of you can relate, I purchased a few too many watches and it’s time to downsize. I’m selling this now discontinued Seiko Prospex SBBN045 Tuna. Fully boxed with all Japanese hang tags, Japanese stamped warranty card dated 2021/8/4, and February 2024 service papers. Reference # is S23629J1 (or in JDM as SBBN045). This reference features Seiko’s 7c46 quartz movement which was (is?) exclusive to the Tunas, a diashield coated case , a sapphire crystal, and black day / date display in both English and Japanese Kanji. This example is in very good used condition (noticeable scratches/ marks on the bezel insert in the right light which I tried to capture). Case measures 47.7 wide and 14.3 thick, with a 48mm lug to lug measurement and 22mm lug width. I hunted for this for quite some time before purchasing it in April. $1,000 shipped in the US, payment via Venmo, PP F&F or wire. No trades, please.

	Established:	1881

	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.
