The BR 03 instrument is born from a simple idea: to turn a cockpit timepiece into the very best aviation watch. Switching, as if by magic, "from the cockpit to the wrist", the BR 03 affords the luxury of overturning the aesthetic codes of contemporary watchmaking, which in turn made it an icon. The BR 03 Chrongraph features a self-winding mechanical Caliber BR-CAL.301 which provides an approximate 40 hour Power Reserve.
