Breitling’s Navitimer B01 Chronograph 43, model AB0138241G1A1, is an iconic pilot’s watch with a rich history dating back to 1952. Designed by Willy Breitling, it featured a circular slide rule for flight calculations. Two years later, it became the official timepiece of the Aircraft Owners and Pilots Association (AOPA), the largest pilots’ club in the world. The Navitimer was embraced by airline captains, aircraft enthusiasts, and even astronaut Scott Carpenter, who wore it in space in 1962. Its appeal extended beyond aviation to celebrities like Miles Davis and Serge Gainsbourg. The latest Navitimer model retains classic features while incorporating modern refinements, such as a flattened slide rule, domed crystal for a sleeker profile, and alternating polished and brushed metal elements for a refined finish. New dial colors in blue, green, and copper, along with the nostalgic return of the AOPA wings at 12 o’clock, highlight the updates. The watch features a stainless steel case, 43mm in diameter, 13.6mm thick, and water resistance up to 3 bars. It houses the self-winding mechanical Breitling 01 caliber with a 70-hour power reserve, 1/4th second, 30-minute, and 12-hour chronograph functions. The cambered sapphire crystal is glareproofed on both sides, and the bezel is bidirectional with a slide rule. The watch comes with a black alligator leather strap and a stainless steel folding clasp. For 70 years, the Navitimer has been a beloved timepiece among aviators and style icons, making it one of Breitling’s most recognizable watches.
