This watch needs no intro. Bought by myself in 2019 and worn as my DD for years. The watch shows signs of its wear with some minor scratches along the bracelet and clasp but wears beautifully. Mechanically the watch is very sound and my only reason for selling is I got an Explorer and this thing has gotten zero wrist time since. Included are original box, card, tool, Sinn Leather strap which I only wore a handful of times, and extra H-links. Shipped fully insured from USA. Willing to meet locally in a public location in Las Vegas NV. Asking 1100 or DM best offer

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.
