In 1967 Heuer developed this largely black chronograph according to specifications from the German military, the Bundeswehr, who wanted to supply their pilots with the watch. In the 1980s and early 1990s Helmut Sinn bought some of these watches from military surplus, revised them and added the SINN logo on the dial. Those timepieces that used tritium luminous material also carried a red "3H" designation.
