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

The Breitling Navitimer AB0139241C1P1 has a lug width of 22mm. This measurement is standard across the entire Navitimer 41mm line and determines the strap width required. Precision is essential: a 20mm strap will sit too narrow with visible lateral play, whilst a 24mm strap will not fit between the case lugs at all.

For the Navitimer AB0139241C1P1, the most coherent materials with the watch's instrument-grade identity are belly alligator leather (regular grain, restrained elegance), vegetable-tanned Italian calf leather (develops patina over time) and solid-colour nylon NATO straps. The strap should measure 22mm at the lug tapering to 20mm at the buckle, ensuring correct proportions with the 41mm case.

To replace the strap on the Navitimer AB0139241C1P1, you will need a flat-blade screwdriver or a dedicated springbar tool to remove the 22mm spring bars securing the strap to the case lugs. Care must be taken not to scratch the polished steel surfaces of the case. If in any doubt, it is advisable to consult a watchmaker or the Casati Milano atelier for a professional strap change.

Yes, any strap with a 22mm lug width is dimensionally compatible with the Navitimer AB0139241C1P1. Milanostraps.it offers a curated selection of Italian handcrafted straps in various leathers and finishes, all produced at 22mm lug width. It is also advisable to check the strap thickness at the lug end to ensure it fits cleanly between the case lugs without forcing.

The lifespan of a leather strap depends on the quality of the tanning process, daily usage and maintenance. A vegetable-tanned calf leather strap worn daily typically lasts between 18 and 36 months before perspiration and mechanical stress compromise the stitching or the keeper. High-quality alligator straps, regularly treated with a neutral leather conditioner, can last considerably longer. Casati Milano provides an 18-month warranty against manufacturing defects.
