eBay find that was a watch box princess. Just replaced the battery. The watch came with the black bezel insert mounted but the original came with it. Visually you can see banged up spring bars, yellowish discolorations at the bezel pip. For the most part the case and crystal look clean. Nothing different from what you should expect a vintage Seiko diver to present with in 2026 after living a prior life of work. I do not know the service history of the watch so I can’t speak to the water tolerance or pressure testing. The previous owner stated they had the dial relumed. Unsure about the hour or minute hands. there is an audible squeak that happens when you turn the crown to set the time. Bezel action is smooth with some give aligning the pip at 12. Selling for $460 shipped with tracking CONUS on a black strap habit NATO. Venmo or PPFF.

	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.
