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

The lug width of the Breitling Navitimer AB0139A71G1P1 is 22mm. This measurement refers to the internal distance between the two lugs of the case and is the key parameter for selecting a compatible strap. Always verify with a digital calliper before purchasing an aftermarket strap.

For the Navitimer AB0139A71G1P1, vegetable-tanned calfskin in havana or cognac enhances the aviator character of the watch and develops an authentic patina over time. Louisiana alligator in black or midnight blue is the ideal choice for formal settings, whilst a ballistic nylon NATO or vulcanised rubber strap is preferable for sport use or variable weather conditions. A 22mm brushed steel ardillon buckle is the most coherent closure with the case finishing.

To replace the strap on the Navitimer AB0139A71G1P1, a dedicated springbar tool is required. Insert the forked tip between the lug and the spring bar, lever inward to compress and release the pin, remove the strap and insert the new one by aligning the spring bar pins with the lug holes. The operation takes approximately two minutes and does not require professional watchmaker intervention, provided the correct tool is used to avoid scratching the steel surfaces.

Yes: any strap with a 22mm lug width and standard length (70/120mm or 75/115mm) is technically compatible with the Navitimer AB0139A71G1P1. The handcrafted straps at milanostraps.it are cut to a tolerance of ±0.2mm and are available in calfskin, alligator, shell cordovan, nylon NATO and vulcanised rubber. Aftermarket build quality can equal or exceed that of the original in terms of materials and finishing.

The lifespan of a leather strap depends on the quality of the hide, the tanning process and daily use. A first-grade vegetable-tanned calfskin strap, with proper care (avoiding prolonged exposure to water and occasionally applying a neutral conditioner), typically lasts between 2 and 4 years under intensive use. Vegetable-tanned alligator, with its denser fibre structure, can last over 5 years. milanostraps.it offers an 18-month guarantee against manufacturing defects on all handcrafted straps.
