Probably the most legendary pilot's watch and the inspiration model for the Navitimer. The first Chronomat came in 1941, although not with the well-known rider's bezel, but with the bezel of the later Navitimer. In 1984, after a break of several years, the Chronomat was re-released with the new bezel, which was intended to protect the Chronomat from glass damage. A special recognition feature here was the Rouleaux bracelet, which disappeared in the early 2000s and was reintroduced in 2020.
