Navitimer

The Breitling Navitimer is a cornerstone of aviation watch history, introduced in 1952 for pilots who needed an on-wrist flight computer. Its signature slide rule bezel, originally developed for the Aircraft Owners and Pilots Association, made it indispensable in the cockpit. Collectors value the Navitimer for its authentic aviation pedigree and enduring design, which has evolved but never strayed from its roots.

Within the Navitimer lineup, the 43mm case size strikes a balance between presence and wearability, housing the in-house Caliber B01 automatic chronograph in most recent references. Key models include the Ref. AB012121 and AB013821, which differ in dial layouts, case finishes, and subtle updates to movement or branding. Earlier models may use third-party calibers, which can affect both value and serviceability.

Pricing varies based on movement (in-house B01 commands a premium), dial color, bracelet vs. strap, and overall condition. Collectible variants often have rare dial colors or limited-edition casebacks. When buying, check for crisp bezel action and well-preserved slide rule scales, as these are both functional and central to the Navitimer’s appeal. Servicing costs are higher for B01 models, but their column-wheel chronograph and 70-hour power reserve make them especially sought-after among modern Navitimers.
