Company history of Sinn

Sinn Spezialuhren was founded in 1961 in Frankfurt am Main by Helmut Sinn, a former pilot and flight instructor. Helmut Sinn was committed to making functional, precise watches for pilots and other professional users. Initially, the company focused on producing aircraft navigation clocks and pilot’s chronographs.

In the 1990s, Helmut Sinn sold the company to Lothar Schmidt, an engineer who had previously worked at IWC Schaffhausen and A. Lange & Söhne. Under Lothar Schmidt’s leadership, Sinn experienced a significant surge in innovation. Many of the technologies and models known today were developed during this period.

Some of Sinn’s most notable models and innovations include:

• Sinn 142: This watch was popular with astronauts and was worn during the first German space mission.
• Sinn UX: A dive watch that is water-resistant to a depth of 12,000 meters and features an oil-filled system that improves legibility underwater.
• Sinn 556: A versatile and robust pilot’s watch, valued for its clear legibility and timeless elegance.

Through its uncompromising quality, technical innovation and focus on functional instrument watches, Sinn has earned a firm place in the watchmaking world. The brand remains a prime example of German watchmaking and engineering, expressed in every one of its products.
