Timestamp/Pics: [https://imgur.com/a/sinn-u50-xBhx806](https://imgur.com/a/sinn-u50-xBhx806) Looking to sell my Sinn U50 (Model 1050.010). I picked up a Pelagos LHD shortly after this and have decided I don’t need both. I wore it a handful of times, but it was clearly worn prior to that from normal wear on the clasp. It is in very good condition, with no crystal scratches (see photos for detail). Timekeeping is on point. **Included:** * Sinn U50 on H-link bracelet (extra links included) * Inner and outer boxes * Manual and warranty card (Purchased from Watch Buys) * Original Purchase Paper Asking $2,000 USD via PayPal to include shipping within CONUS. G&S fee can be covered by the buyer. I’m happy to video chat or provide more info.

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.
