Strap for Navitimer B01 Chronograph 41 Stainless Steel / Mint Green / Alligator - Folding

The Breitling Navitimer AB0139211L1P1 has a lug width of 22mm. This measurement is consistent across the entire Navitimer 41mm range and allows any standard 22mm aftermarket strap to be fitted without adapters.

The ideal strap depends on the intended use: vegetable-tanned calf leather suits everyday wear and develops a distinctive patina over time; flat-grain alligator leather is best suited to formal occasions; a nylon NATO strap honours the aeronautical heritage of the watch and offers excellent durability. All options are available in 22mm at milanostraps.it.

Strap replacement requires a springbar tool. Place the watch face-down on a soft surface, insert the forked tip of the tool between the lug and the spring bar, compress the bar inward and slide the strap free. Repeat on the opposite side. The process takes approximately two minutes and requires no professional equipment.

Yes. Any straight-ended 22mm strap is compatible with the Navitimer AB0139211L1P1. Milano Straps produces handcrafted straps in various materials — leather, alligator, NATO, rubber — with thickness and length tailored to Breitling lugs. No case modification is required.

The lifespan of a leather strap depends on tanning quality, frequency of use and care. A quality vegetable-tanned leather strap, worn regularly and kept away from excessive moisture and perspiration, typically lasts between 2 and 4 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
