was specially designed for air pilots needing a tool to measure short time intervals. Its strap, which is available in beige leather or black ultra-resistant fabric, serves as a reminder of the practical purpose of this camouflage model. The four screws in the corners of the case evoke the aeronautical origins of the BR 01, using the front-mounting system of on board instruments featured in aircraft cockpits. These are functional and secure the bezel to the case, ensuring the watch is water-resistant to a depth of 100 metres.
