Strap for Aviator 8 Chronograph 43 Stainless Steel / Black / Calf / Folding

The Breitling AVI A13316101B1X2 features a 23mm lug width — an uncommon measurement that requires straps specifically cut to this size. A 22mm strap will not fit correctly and will compromise the visual integrity of the case.

For the Breitling AVI A13316101B1X2, the most suitable materials are Hornback alligator leather in tobacco or navy, vegetable-tanned calfskin for those who appreciate a developing patina over time, and two-tone nylon NATO straps to honour the watch's aeronautical heritage. The ideal choice depends on intended use and dial colour.

The strap on the Breitling AVI A13316101B1X2 is replaced using a standard flat-tip or spring-bar tool. The lugs accept a 23mm spring bar. This can be done independently with care, or entrusted to a watchmaker or the Casati Milano atelier to ensure correct fitting without scratching the case.

Yes, high-quality aftermarket straps are available in the 23mm lug width required by the Breitling AVI A13316101B1X2. Casati Milano produces bespoke handcrafted straps tailored to this specification, available in various leathers and finishes, complete with buckle or deployant clasp, and covered by an 18-month manufacturing warranty.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and exposure to perspiration and moisture. A well-crafted strap in vegetable-tanned leather or quality alligator, with appropriate care, can last between three and five years while developing a distinguished patina. Lower-grade or synthetic leather straps deteriorate considerably faster.
