Strap for Navitimer B01 Chronograph 41 Stainless Steel / Mint Green / Bracelet

The Breitling Navitimer AB0139211L1A1 features 22mm lugs. This measurement refers to the internal distance between the two case lugs where the strap attaches. It is one of the most common widths found in professional chronographs and offers a wide compatibility range across leather, textile, and rubber straps.

The ideal choice depends on intended use and aesthetic preference. For formal or collector wear, a vegetable-tanned alligator strap in cognac or midnight blue complements the Navitimer's dense dial without overwhelming it. For everyday use, a vegetable-tanned calfskin strap develops a patina consistent with the instrument-grade character of the watch. For sport or outdoor use, a ballistic nylon NATO strap or vulcanised rubber strap offers the best functional performance.

The strap is replaced by removing the springbar pins connecting it to the case lugs. A springbar tool — a forked pin tool — is inserted laterally between the strap and the lug to compress the spring inside the bar. The operation takes under a minute and requires no watchmaking expertise. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Any strap with a 22mm attachment width and standard springbar pins is compatible with the Navitimer AB0139211L1A1. Milano Straps offers a curated selection of handcrafted Italian straps in this size, made from selected hides with hand-stitched finishing, at a quality level comparable to or exceeding the original. Standard strap length is 120/75mm, suitable for most wrist sizes.

Longevity depends on leather type, frequency of wear, and exposure to perspiration and moisture. A quality vegetable-tanned calfskin strap worn daily with normal care typically lasts 2–4 years. Alligator, being denser and less porous, can exceed 5 years while retaining its grain structure. Avoiding direct water contact and occasionally applying a neutral leather conditioner significantly extends strap life.
