Reluctantly listing my Sinn U50 500 meter diver. Includes full kit. Inner and outer box, strap change tool, Watchbuys warranty card dated Jan 2023 (still under warranty), fitted Sinn rubber strap with short locking clasp. This is the non-tegimented version with tegimented bezel. Back of lugs show very minor marks from strap changes but otherwise I’d rate case as mint/perfect. Bezel turns crisply. Movement running beautifully at +4 per day. Crystal is maybe a 9 out of 10. Maybe the tiniest flea bite in the AR coating, but otherwise perfect. You have to look REALLY close to see it. Rubber strap has been cut and is loose on 6.5” wrist (probably fitted to 6.75”). Clasp works perfect but does have some desk diving marks. Priced at $1700 shipped CONUS. Ships from Utah.

Sinn Spezialuhren GmbH is a manufacturer of mechanical wristwatches based in Frankfurt am Main. The company was founded in 1961 by flight instructor and pilot Helmut Sinn under the name ‘Helmut Sinn Spezialuhren’.

Following its foundation in 1961, the company focused on the manufacture of navigation cockpit clocks and pilot chronographs and sold these through direct selling, bypassing retailers. The clocks and watches were produced according to pilot Helmut Sinn’s specifications in the private label sector in Switzerland. By eliminating the trade margin of the retailers, the company was able to offer its clocks and watches at a lower price than through traditional sales channels.

In 1994, Helmut Sinn sold the company to Lothar Schmidt. Following the sale, he acquired Swiss watchmaker Guinand in 1996. In 1998, he set up a new company in Frankfurt am Main. With this company, he offered brand watches from Jubilar, Chronosport and the newly acquired Guinand. In 2006, he retired from business activity. Since handing over the management of the business to his long-standing employee Horst Hassler, he now acts as an advisor to the company. On September 3rd 2016 Helmut Sinn celebrated his 100th birthday.
