FS: Sinn U50 S Black MOP Mother of Pearl Ltd

Here is a rare one. This is the blacked out 41mm mother of pearl dial that hardly ever pops up for sale. 11.5 thick, date function, automatic movement. Bezel action so crisp. This thing is so comfy on wrist. Pictures don’t do the dial justice. This comes as full and complete set as purchased directly by me from watchbuys. Great condition, no noteworthy blemishes to disclose. Hardly worn ever! Dated Feb 2022.
NO TRADES, US ONLY. Comes with free registered usps insured shipping. Price is $3,999.

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.
