Strap for Navitimer B01 Chronograph 43 Stainless Steel / Black / Alligator - Folding

The Breitling Navitimer AB0138211B1P1 features a 22 mm lug width. This measurement, taken between the two lugs of the case, ensures compatibility with the broad range of 22 mm aftermarket straps available on the market.

The ideal choice depends on the intended context. For formal wear, an alligator strap with vegetable tanning complements the in-house B01 calibre. For daily use, Italian calf leather with contrast stitching preserves the model's aviator aesthetic. A nylon NATO strap is historically consistent with the watch's aeronautical heritage.

The strap is removed using a fine-tipped spring bar tool, releasing the 22 mm spring bars housed within the lugs. The operation takes approximately two minutes and requires no specialised equipment. It is nonetheless advisable to consult a watchmaker to avoid scratching the case.

Yes. Any strap with a 22 mm attachment is technically compatible with the Navitimer AB0138211B1P1. Milano Straps offers a curated selection of handcrafted straps in various materials — leather, rubber, NATO — all produced with a 22 mm lug width and finished by hand in Italy.

Longevity depends on the type of leather, frequency of wear, and exposure to perspiration and humidity. A quality calfskin strap, regularly conditioned with a nourishing cream, typically lasts 2–3 years. An alligator strap with vegetable tanning, being more resilient, can exceed 4–5 years while retaining its original patina.
