Strap for Navitimer B01 Chronograph 43 Stainless Steel / Green / Boutique Edition

The lug width of the Breitling Navitimer AB01384C1L1P1 is 22 mm. This measurement is taken between the two lugs at the point where the strap attaches to the case, using a calliper or a ruler. Breitling has maintained this 22 mm standard across several generations of the Navitimer to ensure compatibility and aesthetic continuity.

The choice depends on intended use and aesthetic preference. A polished alligator strap enhances the chronograph's formal register; a vegetable-tanned calfskin develops an authentic patina over time; a ballistic nylon NATO strap references the model's AOPA aeronautical origins; vulcanised rubber is suitable for intensive sporting use. In all cases, the lug width to observe is 22 mm.

The strap is secured by standard 22 mm spring bars. To replace it, use a spring bar tool to compress each bar within its lug seat, remove the old strap and fit the new one. No specialist tools are required, though care should be taken to avoid scratching the steel lugs during the operation.

Yes. Any strap with a lug width of 22 mm is technically compatible with the Navitimer AB01384C1L1P1. Milano Straps offers a curated selection of handcrafted leather, nylon and rubber straps made specifically for this width, with finishes and materials chosen to complement the aesthetics of the Breitling chronograph.

Longevity depends on the leather type, frequency of use and maintenance. A quality vegetable-tanned calfskin strap, worn daily and kept away from excessive moisture and perspiration, typically lasts 18 to 36 months. Alligator or shell cordovan straps, being denser and more compact materials, can exceed 3 to 5 years. Milano Straps provides an 18-month warranty against manufacturing defects on all its straps.
