Navitimer B01 Chronograph 43

The Breitling Navitimer B01 Chronograph 43 (ref. AB0138241B1A1) presents one of aviation watchmaking's most storied silhouettes in a 43 mm stainless steel case with a black dial and silver-toned subdials. At its heart beats the manufacture Calibre Breitling 01, a column-wheel chronograph movement developed entirely in-house. The combination of the iconic circular slide rule bezel and a high-grade proprietary movement places this reference firmly at the top of the modern Navitimer hierarchy.

The Navitimer name traces its origins to the 1950s, when Breitling introduced a pilot's chronograph with an integrated circular slide rule capable of performing the airborne calculations demanded by professional aviators. Decades of continuous production made the Navitimer one of the longest-running chronograph lines in the industry. The introduction of the in-house Calibre B01 marked a pivotal moment for the brand, signalling a transition from reliance on third-party ebauches to full manufacture status. The AB0138241B1A1 variant, entering production in 2022, carries that heritage into the contemporary era with modern finishing standards and movement refinement.
