Asking $2250 shipped within CONUS Card Dated 2018. Comes with box/papers/extra links. Case shows a fair amount of wear all around. Tried to capture it in the pictures. There is a nice little chip on the lower part of the 9 o’clock side of the case that you can’t see unless the watch is off. Crystal is in excellent shape no noticeable flaws. The H-Link is also in excellent shape, barely any wear. I swapped out the beat up fine link it came on for a better condition H-Link. Message with any questions or for additional photos. Thanks!

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.
