Hello, I’m looking to sell my Seiko Prospex Alpinist SPB121. This was purchased brand new from an authorized dealer within the past month or so and includes the full set with boxes, papers, and warranty as expected. I’ll also include the Fluco Horween shell cordovan strap as shown. The condition is consistent with a few weeks of total wear. Small scuffs here and there on the polished portions perhaps, but nothing notable. I’m looking for $485. No trades. Please do your research and confirm your intent and ability to complete the purchase prior to reaching out. If you’re a buyer, please email me at [email protected] or message me here. Payment via PayPal, Zelle, or wire. Shipping is included in my price.

Excellent Deal with WatchOutChicago!

I bough an expensive watch from WatchOutChicago and it was a smooth transaction from start to finish. Communication was prompt and respectful before, during, and after the transaction. Shipping was prompt, and he also followed up once I received the watch to ensure all was well. I would not hesitate …

Highly recommend WatchOutChicago

**WatchOutChicago was top notch. He responded quickly, provided pictures when requested, and shipped the watch the same day that we made the deal. I highly recommend him to other buyers.**

Excellent transaction with WatchOutChicago!

Recently bought a watch from WatchOutChicago - couldn't have been a more perfect transaction, from the quick communication, to the fast shipping, to some after-sale follow-ups that he frankly didn't have to entertain but went out of his way to assist me. Wouldn't hesitate to deal with again!

	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.
