Strap for Navitimer 1461 Stainless Steel / Black / Bracelet

The Breitling Navitimer A1937012/BA57/443A has a lug width of 24mm. This is a non-standard measurement in the aftermarket sector. Before purchasing a replacement strap, always verify this dimension using a digital calliper by measuring the internal distance between the two horizontal lugs of the case.

For a 46mm case with a complex dial and perpetual calendar, the most suitable materials are bombé alligator in black or tabac brown, vegetable-tanned calf leather for those seeking a natural patina over time, and shell cordovan for maximum density and resistance. A steel deployant clasp is recommended to distribute the weight of the case evenly across the wrist.

Changing the strap on the Navitimer requires a fine-tip spring bar tool. The 24mm spring bars must be removed carefully to avoid scratching the stainless steel case. It is advisable to work on a soft surface and, if in doubt, to entrust the operation to a watchmaker or the Casati Milano atelier for a professional, risk-free service.

Yes. Milano Straps crafts bespoke straps specifically calibrated for the 24mm lug width of the Navitimer. Each strap is made to measure, accounting for the geometry of the original Breitling lugs, ensuring a correct fit without play or tension. The full collection is available at milanostraps.it/collections/cinturini-orologi-per-misura-ansa-24mm.

Longevity depends on the material and usage. A quality vegetable-tanned calf leather strap has an average lifespan of 18 to 36 months with daily wear. Shell cordovan, owing to its dense fibrous structure, can exceed three years. Well-maintained alligator, treated with nourishing cream, can comfortably reach two to four years. Perspiration and moisture are the primary factors in deterioration: leather straps are not recommended during intense physical activity.
