History of SINN

In 1961, Helmut Sinn, a former World War II pilot and instructor for blind flight, founded Helmut Sinn Spezialuhren in Frankfurt am Main for manufacturing navigation clocks and pilot chronographs. In 1985, the German physicist and astronaut Reinhard Furrer wore a Sinn wrist watch during the D-1 Spacelab mission. In 1994, Lothar Schmidt acquired the company and retitled it to “Sinn Spezialuhren GmbH.”

Sinn has been renowned for its enduring quest for innovation. Many of the innovations were introduced under the outstanding leadership of Lothar Schmidt. In 1994, the brand developed a titanium watch with Magnetic Field Protection and a freely oscillating suspended movement. In 1995, the first watch with Ar-Dehumidifying Technology was introduced. This notable innovation protects the timepiece from fogging and improves functional reliability.

In 1996, the first sinn watch with HYDRO Technology was introduced. Applicable only for quartz diving watches, this technology need to immerse the movement, dial and hands with special oil. It ensures excellent pressure resistance and protects the timepiece from fogging.

This innovation also improves visibility of the dial so that it can be read at any angle under water. Along with Ar-Dehumidifying Technology, this special oil also improves the temperature resistance of the timepiece. The brand unveiled its first Mission timer (EZM1) in 1997. After a couple of years, Sinn brought in the famous Frankfurter Financial District Watch.

In 2004, Sinn introduced DIAPAL Technology, which ensures the lubricant-free operation of the Swiss lever escapement. The brand introduced TEGIMENT technology in 2003 and Black Hard Coating in 2006.

In 2005, the company began manufacturing diving watches with German submarine steel. These dive watches have been certificated by Germanischer Lloyd, Hamburg (now DNV GL). In 2008, the brand introduced Captive Safety Diver´s Bezel, which incorporates a patented mechanism for ensuring additional protection against accidental misalignment of the unidirectional bezel.

In 2010, Sinn introduced its first Damascus steel watch. In 2011, the brand celebrated its 50th anniversary. In 2012, the company introduced new pilot wristwatches certified by TESTAF, the first technical standard for pilot watches. Based on this new benchmark, the German Institute for Standardization formulated DIN 8330 standard for pilot watches. On 1st September 2017, the company opened its current headquarters in Frankfurt Sossenheim.
