For sale is this Seiko Prospex 3rd Gen "Sumo". I purchased this watch new in 2021, via Amazon. Condition: Good used condition. I have worn it about 50 times, so there are some scratches and general wear. Comes with: Box, original papers, and spare links for the bracelet (see photos). Photos: https://imgur.com/a/vppxlvM Price: $350 shipped inside US, w/ tracking Payment: PayPal F/F Not looking for trades at this time. Note: It’s my first transaction on watchexchange, but I have confirmed transactions on another classifieds subreddit, and I have a substantial public feedback thread on Facebook for another classifieds group, as well. About this Sumo model: The model is nicknamed by the Seiko community as “Green Sumo” or “Hulk.” The third generation Sumo’s have a sapphire crystal. The Sumo is not a small watch — thus the nickname! But for the price (even the retail price) I believe it is a fantastic value for a dive watch.

	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.
