History of Sinn Watches

Founded in 1961 by Helmut Sinn, a former World War II pilot and blind flight instructor, Sinn Watch Company quickly gained recognition for its aviation-inspired timepieces. Specializing in navigation clocks and pilot chronographs, Sinn's reputation for precision and durability was cemented during the 1980s and 1990s when their watches accompanied German astronauts on several space missions. These accomplishments demonstrated the brand's commitment to creating reliable timepieces capable of withstanding extreme conditions.

A new era began in 1994 when certified engineer Lothar Schmidt acquired the company, introducing significant technological advancements. Under Schmidt's leadership, Sinn pioneered innovations such as Ar-Dehumidifying Technology, DIAPAL lubrication-free escapements, and TEGIMENT hardened steel cases. Today, Sinn remains at the forefront of horological innovation, producing high-quality timepieces that blend traditional craftsmanship with cutting-edge technology. The brand's dedication to excellence and continuous improvement ensures its lasting legacy in the world of high-end watchmaking.
