Hello, up for sale is my pre-owned Sinn 103 with beautiful vibrant sunburst blue dial and matching anodized bezel which is more striking than many standard 103s that are often matte or very utilitarian in color. The ivory color of the hands and numerals adds a warm contrast to the blue, making it feel classic without being aged. Limited to only 500 pieces this is a standout piece amongst the 103 collection. See below for specs: - 41mm case - 20mm lug width - 16mm thick - Valjoux 7750, 42 hour PR - Shock resistant - Anti-magnetic - Low pressure resistant - 200M Water Resistant - Sapphire sandwich with AR - 500 limited mark on rotor Watch comes with original kit including box, manual, warranty card dated 2019 in booklet, and Sinn tool. History unknown but wouldn’t be surprised if this was recently serviced, time keeping is great at -6 spd and 290-300 AMP! (See link below for time graph data). Pricing to sell at $2600 shipped, there is only one other listed on C24 for over $4k. Feel free to reach out with any questions or requests. Thanks for looking, no trades please!

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.
