The Navitimer is the most recognized pilot's chronograph in the world and one of the longest-running watch designs in production. The circular slide rule bezel isn't decoration, it's a functional aviation computer. The B01 variant runs Breitling's first fully in-house movement, built to COSC chronometer standards.

The History

Breitling introduced the Navitimer in 1952 in partnership with the Aircraft Owners and Pilots Association (AOPA). The defining feature, the circular slide rule bezel, allows pilots to perform flight calculations including fuel consumption, speed, distance, and rate of climb without any other tools. It was designed as a cockpit instrument worn on the wrist, and that functional heritage is woven into every detail of the dial. The watch became the choice of professional aviators and remains certified by AOPA to this day. The B01 variant, introduced in 2009, marked a turning point: it was the first Navitimer to run an in-house movement rather than a third-party caliber. The Breitling Caliber 01 is a COSC-certified column-wheel chronograph with a 70-hour power reserve and vertical clutch, built entirely in Breitling's own manufacture.

Why Buyers Want It

The Navitimer B01 43 is one of the strongest value propositions in its category. You get a genuine in-house manufacture chronograph movement, decades of aviation heritage, and immediate brand recognition, at a pre-owned price point that significantly undercuts comparable Swiss chronographs. The dial is complex and confident without being aggressive. It wears well both as a tool watch and a dress piece. On the secondary market it has held value reliably without the speculation-driven volatility seen in Rolex references, making it a lower-risk purchase for buyers entering the pre-owned market.

What to Look For When Buying Pre-Owned

The Navitimer's complex dial and slide rule bezel create multiple potential failure points on pre-owned examples. Inspect carefully.

, Slide rule function, rotate the outer bezel and verify it moves smoothly with even resistance. A stiff or grinding bezel indicates damage or debris in the bezel track.
, Chronograph pushers, actuate both pushers and verify crisp action with clean return. The B01's column wheel mechanism should feel precise. Mushy or uneven pushers indicate movement issues.
, Dial condition, the Navitimer dial has dense typography and multiple sub-dials. Check each register under magnification for correct printing and consistent lume application.
, Reference verification, many Navitimer variants exist. Verify the reference number on the caseback matches what's listed and matches the papers if present.
, Movement service, ask for service records on any example over 5 years old. The Cal. B01 is reliable but the complexity of a column-wheel chronograph benefits from documented maintenance.
