Breitling Navitimer 1 B01 Chronograph

The Navitimer is the most functional dial in watchmaking. Its circular slide rule, developed with the Aircraft Owners and Pilots Association in 1952, let aviators calculate fuel burn, rate of climb, distance and unit conversions in flight — and it still works exactly as designed. This 41mm steel reference pairs that rotating bezel with a chronograph driven by the Manufacture Calibre 01, an in-house automatic with column wheel and vertical clutch, COSC-certified and visible through the sapphire caseback.
