Strap for Navitimer Ref 806 1959 Re-Edition Red Gold

The Breitling Navitimer RB0910371B1X1 has a lug width of 20mm. Before purchasing an aftermarket strap, it is always advisable to verify this measurement using a digital calliper placed internally between the lugs, flush against the case, to account for any variation caused by the curved lug profile.

For a red gold case such as that of the Navitimer RB0910371B1X1, vegetable-tanned alligator straps in cognac, bordeaux or tobacco tones offer the most aesthetically coherent pairing. Shell cordovan is a refined alternative for those seeking a compact surface with waxy reflections. For sporting contexts, a quality vulcanised rubber strap provides durability and comfort without compromising on construction quality.

Strap replacement requires a lever-type spring bar tool or fine-tipped instrument to depress the spring bar button within the lugs. Given the precious red gold case, it is advisable to protect the case surfaces with low-residue masking tape before proceeding, or to entrust the operation to a watchmaker or specialist atelier to avoid scratching the lugs.

Yes. The standard 20mm lug width allows the use of any aftermarket strap with this interaxis. For the red gold Navitimer, it is recommended to choose straps with pre-curved ends that follow the case profile, eliminating the visual misalignment between case and strap that occurs with standard flat-end terminations.

The lifespan of a leather strap depends on the tanning process, frequency of use, and exposure to perspiration and environmental factors. A quality handcrafted vegetable-tanned alligator strap, with daily use and proper care (nourishing cream every 3–4 months, drying away from heat sources), maintains structural and aesthetic integrity for 3–5 years. Shell cordovan, being denser and more compact, tends to offer greater longevity.
