Lemania 5100

The Lemania 5100 is an automatic chronograph introduced in 1978. It features a central minutes counter, running seconds, and a 12-hour register. The movement is known for its robustness and has been used in military applications by Sinn and Tutima, as well as in racing and space contexts. Production ceased following the Swatch Group's integration of Lemania, though it continued briefly for outstanding contracts.
