Taking inspiration from the first Chronomat watches of 1941, the Chronomat is created and named after a chronometer designed for mathematicians. Having gifted the slide rule to the Navitimer, the Chronomat went on to become the ultimate timepiece for land, sea or air. With its stylish bullet bracelet and uni-directional rose gold rotating bezel, this steel case offers professional performance and luxury. Its charismatic white dial gives its wearer perfectly clear legibility, with Super-LumiNova® coated rose hour markers. Water resistant to 100m, this calibre B10 is a 100% Swiss made, self-winding timepiece boasting a 42-hour power reserve.
