Pre-owned Navitimer B01 Chronograph 46 ref AB0137241L1A1 (2024). The Navitimer’s story began in 1952, when Willy Breitling developed a chronograph equipped with a circular slide rule that allowed pilots to perform critical flight calculations directly from their wrist. Two years later, the Aircraft Owners and Pilots Association (AOPA) adopted it as its official timepiece, cementing the Navitimer’s place in aviation history. Over the decades, it would find its way onto the wrists of airline pilots, astronauts, and cultural icons alike, becoming one of the most recognizable watches in the world. The modern watch you see here is instantly identifiable as a Navitimer. The signature slide rule bezel still surrounds the dial, preserving the watch’s instrument-like appearance and deep connection to aviation. Breitling refined the design with a flatter slide rule and domed crystal that create a sleeker profile than previous generations, while alternating brushed and polished surfaces add a touch of sophistication to the substantial 46mm case.
