Founded in 1961

Helmut Sinn, an instructor for blind flight and former World War II pilot, founds the company “Helmut Sinn Spezialuhren” in Frankfurt am Main. The company’s core business is the manufacture of, navigation clocks and pilot chronographs.

Since its founding in 1961, the company has focused on high-quality, mechanical watches. When certified engineer Lothar Schmidt acquired the company in 1994, he ushered in a new era of technological development.

“For some, time is a philosophical concept. For others, it’s a precisely measurable unit. For SINN, it is both. Sinn watches unite traditional fine craftsmanship with pioneering innovations.

The result: Sinn timepieces that people can rely on throughout their lives and that guarantee the highest precision even under extreme conditions. This reliability of Sinn watches can be experienced firsthand and verified by objective methods.”
