About Sinn:

Sinn was founded in Frankfurt, Germany, in 1961. Helmut Sinn, a German Air Force pilot and flight instructor, began making pilot instruments and wristwatches. In September 1994, engineer Lothar Schmidt took over the management of Sinn, developing numerous Sinn technologies and unique materials.

The official name of Sinn, 'Sinn Spezialuhren,' translates to 'Sinn Special Watches' in Japanese, and its product policy is the uncompromising pursuit of functionality through traditional, precise watchmaking techniques and innovative exploration.

In addition to its headquarters in Frankfurt, Sinn has evolved by establishing the group's case manufacturing company SUG in Glashütte, Saxony, and a repair center in Dresden.

Sinn watches are highly trusted by professionals worldwide, including pilots, divers, and the German Federal Police's special unit GSG 9, proving their high practicality in harsh environments.
