Detailed Description

The Breitling Navitimer is one of the most storied chronographs in aviation history. Introduced in 1952, it quickly became favored by pilots for its built‑in circular slide‑rule bezel, which allowed for vital in‑flight calculations. This modern iteration, the Navitimer 01 Chronograph 43, executes that design masterfully with contemporary proportions and Breitling’s high‑performance in‑house Caliber B01 movement.

This reference features a black dial contrasted by three silver sub‑registers, giving it the timeless “reverse panda” look that perfectly balances classic and modern aesthetics. The polished stainless‑steel case and sophisticated alligator strap make it suitable for both business and casual settings, while the slide‑rule bezel distinguishes it instantly as a Navitimer.

A domed sapphire crystal with anti‑reflective coating ensures excellent visibility under any lighting, and the large crown and pump pushers deliver satisfying tactile feedback. Powering the watch is Breitling’s in‑house Caliber B01, praised for its 70‑hour power reserve, column‑wheel chronograph design, and COSC‑certified accuracy.

Historical Significance

The Navitimer isn’t just a chronograph—it’s a symbol of mid‑century aviation design. As the preferred chronograph of pilots since the 1950s, its slide‑rule bezel became an essential instrument before modern flight computers. The B01 generation, launched in 2009, marked Breitling’s full transition to manufacture movements, blending historic spirit with technical excellence.

The inclusion of both the old‑style and new‑style warranty cards with this example represents a moment in Breitling’s history when the brand was transitioning its documentation systems, making this particular set noteworthy for collectors.
