Strap for Aviator 8 Automatic 41 Stainless Steel / Blue / Calf / Pin

The Breitling AVI reference A17315101C1X1 has a lug width of 21mm. This is a specific measurement that does not match the most common standard sizes (20mm or 22mm). It is essential to verify this dimension before purchasing an aftermarket strap by measuring the internal gap between the lugs with a millimetre ruler once the original strap has been removed.

For the Breitling AVI A17315101C1X1, the most suitable straps are vegetable-tanned alligator (for a bespoke, sartorial register), shell cordovan (for those who value leather quality and long-term patina development), smooth calf leather, or nylon NATO for everyday and sport use. The choice depends on the intended context and the chromatic pairing with the dial.

To replace the strap on the Breitling AVI A17315101C1X1, a fine-tipped spring bar tool is required to remove the spring bars securing the strap to the lugs. Care must be taken to avoid scratching the case surfaces. If in doubt, it is advisable to consult a watchmaker or visit the Casati Milano atelier.

The lifespan of a leather strap depends on the material, care, and frequency of use. A high-quality vegetable-tanned alligator strap, kept away from prolonged moisture and periodically treated with appropriate leather conditioner, can last between 3 and 6 years. Shell cordovan is among the most durable and long-lasting leather options. Casati Milano straps carry an 18-month warranty against manufacturing defects.
