Sinn is a Frankfurt tool-watch maker founded in 1961 by pilot and instructor Helmut Sinn, and since 1994 led by former IWC engineer Lothar Schmidt. The house is defined by function-first engineering: tegiment surface hardening, dehumidifying Ar-dry technology, temperature-resistant oils, and the EZM mission timers developed with police and special units in mind.
