Navitimer B09 Chronograph 41

Created in Breitling’s characteristic modern-retro style, the manual-wound Navitimer B09 Chronograph 41 brings the spirit of the iconic Twin Jet Navitimer of the 1960s to the core collection. Developed in 1952 for the Aircraft Owners and Pilots Association (AOPA), the Navitimer combined a circular slide rule with a chronograph, letting aviators perform calculations with the twist of a bezel and track elapsed time at the press of a pusher. As the first core collection Navitimer powered by the manual-wind caliber B09, this iteration takes direct inspiration from the 1960s reference worn by racecar drivers Jim Clark and Graham Hill, both former aircraft pilots who understood the usefulness of the Navitimer’s slide rule and chronograph and brought its utility to the track. The 41mm case houses either a black or blue dial with white contrasting subdials and the signature slide rule. With the Twin Jet logo front and center, the dial revisits the emblem first seen on the 1965 Navitimer. It served as the civilian counterpart to the AOPA logo, which was used in the models retailed directly to their members.
