FAQ

What is the lug width of the Breitling Avenger A1337011.C757.135A?

The lug width of the Breitling Avenger A1337011.C757.135A is 20 mm. Despite the 48.40 mm case diameter, Breitling opted for a standard 20 mm lug width, ensuring full compatibility with the wide range of aftermarket straps available in this size.

What is the best strap for the Breitling Avenger A1337011.C757.135A?

For the Breitling Avenger A1337011.C757.135A, the most suitable straps are vegetable-tanned alligator (for artisan warmth and long-term patina development), vulcanised rubber (for intensive or aquatic use), and ballistic nylon NATO (for maximum fidelity to the aviation aesthetic). Shell cordovan is the choice for a sober, compact profile. The lug width is 20 mm.

How do you change the strap on a Breitling Avenger A1337011.C757.135A?

To replace the strap on the Breitling Avenger A1337011.C757.135A, use a flathead screwdriver or a spring bar tool to remove the 20 mm spring bars housed in the lugs. It is advisable to work on a soft surface to avoid scratching the satin-finished stainless steel case, and to use a non-metallic tip on the dial side. The operation takes approximately 2–3 minutes for an experienced hand.

Is there an aftermarket strap compatible with the Breitling Avenger A1337011.C757.135A?

Yes. Any strap with a 20 mm lug width and standard spring bars is compatible with the Breitling Avenger A1337011.C757.135A. Milanostraps.it offers a selection of handcrafted straps in 20 mm, made by hand in the atelier using selected materials, compatible with this Breitling reference without the need for adapters.

How long does a leather strap last on a Breitling Avenger A1337011.C757.135A?

The lifespan of a leather strap depends on the material and usage. A quality vegetable-tanned alligator strap, with daily wear and proper care (kept away from water and excessive perspiration), typically lasts 2–4 years before showing significant signs of wear. Shell cordovan, due to its dense and fibrous structure, tends to last longer while developing a distinctive patina. Casati Milano offers an 18-month warranty against manufacturing defects.
