Strap for Navitimer 01 46 Stainless Steel / Aurora Blue / Bracelet

The lug width of the Breitling Navitimer AB012721.C889.443A is 24 millimetres. This dimension is specific to the Navitimer with a 46mm case and ensures harmonious proportions. To verify compatibility, measure the distance between the two attachment holes on the case lugs: it should correspond exactly to 24mm.

For the Navitimer AB012721.C889.443A, we recommend straps in alligator (fine grain, elegant), vegetable-tanned calfskin (natural patina develops over time), or shell cordovan (exceptional durability). The most appropriate colours are dark brown, deep black, and anthracite grey, which respect the authority of the case without appearing decorative.

The strap is secured to the case lugs via removable spring bars. Using a spring bar tool, gently press the small piston beneath the pin to release the internal spring mechanism. Extract the pin and the strap will come free. Insert the new strap and reposition the pin. No precision tools are required; only care and caution.

Yes, any 24mm strap is compatible with the Breitling Navitimer AB012721.C889.443A, provided the case lugs properly accommodate the spring bars (typically 1.8mm diameter). Artisan straps from Milano Straps are manufactured with certified tolerances to guarantee precise fit without play or slack.

Longevity depends on material and usage patterns. Vegetable-tanned calfskin lasts 2–4 years with daily wear, developing visible patina. Alligator can exceed 5 years. Shell cordovan reaches 7–10 years. Artisan straps include an 18-month warranty against manufacturing and stitching defects. At Casati Milano, repairs and finishing services (buckle elasticity, updates) are available for life.
