Strap for Navitimer 1 B01 Chronograph 46 Stainless Steel / Aurora Blue / Croco / Folding

The Breitling Navitimer AB0127211C1P2 (46mm case) features a lug width of 24mm. This is a non-standard measurement compared to conventional production, requiring a targeted strap selection. It is advisable to verify the lug width with a digital calliper positioned between the inner lug surfaces before purchasing a replacement strap.

For the Navitimer 46mm, the most suitable materials are vegetable-tanned alligator — ideal for formal or collector use — and grained calf leather for everyday wear. NATO nylon straps are narratively consistent with the watch's aeronautical heritage. The final choice depends on intended use and the desired aesthetic register.

Strap replacement is carried out via the spring bars connecting the strap to the case lugs. A dedicated spring bar tool is required to release the bars and fit the new 24mm strap. It is recommended to work on a soft surface to avoid scratching the stainless steel case, and to ensure the spring bars are correctly seated before wearing the watch.

Yes, quality aftermarket straps compatible with the Navitimer 46mm's 24mm lug width are available. Milano Straps offers a dedicated selection in leather, nylon and rubber, crafted from carefully sourced materials and available online. For a bespoke strap with direct leather selection, the Casati Milano atelier offers a made-to-measure service by appointment.

The lifespan of a leather strap depends on the material, tanning quality and frequency of use. A high-quality vegetable-tanned alligator strap can last between three and six years with regular wear, developing a distinctive patina over time. Frequent exposure to water and perspiration reduces longevity: in such cases, alternating with a NATO or rubber strap is advisable.
