Breitling Navitimer 1 B01 Chronograph

The Navitimer carries 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 mid-flight — and it still works exactly as designed. This 43mm steel reference gives that bezel room to breathe, paired with a chronograph driven by the Manufacture Calibre 01, in-house, COSC-certified and shown through a sapphire caseback.
