Strap for Navitimer B01 Chronograph 41 Stainless Steel / Black / Alligator

The Breitling Navitimer AB0139211B1P1, housed in a 41 mm stainless steel case, features a standard lug width of 22 mm. This measurement should be taken with a digital calliper across the inner distance between the two lug horns, at the point closest to the case.

For the Navitimer AB0139211B1P1 with a black dial, a vegetable-tanned cognac or tobacco calf leather strap with beige stitching is the most historically coherent choice, reflecting the model's vintage aviation aesthetic. Alternatively, a black alligator belly strap with a stainless steel deployant clasp offers a more formal register without compromising the instrument-watch character of the piece.

Strap replacement on the Navitimer AB0139211B1P1 is carried out via standard 22 mm spring bars. Using a forked springbar tool, compress the spring bar within the gap between the lug and the strap end, then slide the strap outward. No case opening is required. The procedure is straightforward but should be performed on a soft surface to prevent case or lug scratches.

Yes, any strap with a 22 mm attachment and standard spring bars is compatible with the Navitimer AB0139211B1P1. MilanoStraps offers a curated range of 22 mm handcrafted straps in calf leather, alligator, rubber and nylon, selected for dimensional compatibility and aesthetic suitability with this Breitling reference.

The lifespan of a leather strap depends on tanning quality, frequency of use, and exposure to perspiration and weather. A quality vegetable-tanned calf strap worn daily and rotated with at least one other strap will typically maintain structural integrity and appearance for 2 to 4 years. High-grade alligator straps, properly cared for with reptile-specific conditioner, can exceed 5 years of service.
