Album here: https://imgur.com/a/8ku3enu This is a hefty piece of watch, feels too big to me, decided to sell. This is the SDR (black hard coated bezel) and Tegimented version of U1. The triangle on a straight line at the case back indicates it's Tegimented. I bought this one in used condition, only wore it a handful of times. I'm including everything I received when I bought it: papers, travel pouch, thread lock, watch tool and a very high quality canvas strap from Red Rock straps. I'm including an extra Sinn travel case, and 3 rubber straps. The two curve-end straps (pure black one and pure red one) can be installed on the watch without any gap, though not as high quality as the official strap, they are quite soft and comfortable. According to last owner the outside anti reflective coating was removed from the crystal. This doesn't affect a normal use at all. You would see non-uniformity, kind of like slight water stain on glass, only under certain light condition at the center of the crystal. The watch runs perfectly. The only blemish l could tell would be the slightest scratch at 55 mark on the bezel, see photo. I'm asking $1800 including USPS priority shipping to CONUS. PPFF only.

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.
