Founded in 1961, Sinn Spezialuhren is one of the younger companies in the luxury watch world. The company, founded by flight instructor and pilot Helmut Sinn, is definitely not unknown. In keeping with the founder, initially only on-board clocks were produced for aircraft, including for the Bundeswehr. Sinn also sold its first wristwatches exclusively for pilots and flight instructors through direct sales. From Eurofighters to Boeing passenger planes, they all had Sinn on-board clocks installed from the 1970s onwards. In keeping with the name "Special Watches", Sinn has focused more on the development of new technologies than simply building trendy watches. Including temperature resistance technology, anti-reflective glass for divers, magnetic field protection and much more.
