Breitling Endurance Pro 38

Breitling's Endurance Pro 38 X83310F61B1S1 is a chronograph with a 38 mm case built from Breitlight, a carbon-based material valued for its light weight. The case measures 12.1 mm thick, with lugs set 18 mm apart. Inside is the Breitling Calibre 83, a thermocompensated SuperQuartz movement certified as a chronometer, driving a chronograph with small seconds and a date function shown through a dial aperture. The black dial sits under a sapphire crystal. A rubber strap closes on a tang-type buckle. The case favours light weight over bulk, making the watch easy to wear through a full workout. It stays water resistant to a depth of 100 metres.
