Strap for Aviator 8 Automatic 41 Stainless Steel / Black / Calf / Folding

The lug width of the Breitling AVI A17315101B1X2 is 21mm. This is a slightly non-standard measurement: it is important to verify it with a digital calliper placed internally between the lugs before purchasing an aftermarket strap, to avoid forced fitting or unwanted play.

For the Breitling AVI A17315101B1X2, the most suitable materials are matte alligator leather, vegetable-tanned calfskin in a vintage finish, and ballistic nylon NATO straps. These materials respect the instrument-grade, aeronautical character of the watch. Dark tobacco brown or matte black are the most coherent colour choices given the black dial.

To replace the strap on the Breitling AVI A17315101B1X2, a springbar tool is required to compress the spring bars within the lug slots. No specialist watchmaking skills are needed, but it is advisable to work on a soft surface to avoid scratching the case. The 21mm lugs accept standard 1.8mm diameter spring bars.

Yes, numerous aftermarket straps are compatible with the Breitling AVI A17315101B1X2, provided they have a 21mm lug width. Milanostraps.it offers a dedicated selection of 21mm straps in various materials — leather, NATO, rubber — with tang buckles or deployant clasps, all crafted with artisanal techniques and directly compatible with this model's lugs.

The lifespan of a leather strap depends on the material and maintenance. A quality vegetable-tanned calfskin strap, worn daily, typically lasts 18 to 36 months before showing significant wear. Equine shell cordovan and alligator, due to their denser fibre structure, tend to last considerably longer. Prolonged exposure to water and perspiration should be avoided, and periodic conditioning with appropriate products is recommended. Casati Milano provides an 18-month guarantee against manufacturing defects.
