Strap for Super Avenger II Stainless Steel / Mariner Blue / Calf / Pin

The lug width of the Breitling Avenger A1337111/C871/443X/A20BA.1 is 24mm. This measurement is standard across the Avenger 48mm line and allows fitment of any aftermarket strap with a 24mm attachment, including leather, NATO, rubber, and deployant buckle options.

For the Breitling Avenger 48mm with a 24mm lug width, the most suitable materials are vegetable-tanned calf leather for daily wear, bombée alligator for formal or semi-formal occasions, and ballistic nylon NATO or vulcanised rubber for sport and aquatic use. A 316L stainless steel deployant clasp is recommended to reduce wear on the strap and allow single-handed fastening.

To replace the strap on the Breitling Avenger A1337111/C871/443X/A20BA.1, use a precision dual-tip spring bar tool or a soft-tipped lever to avoid scratching the steel lugs. Compress the spring bars inward and slide the strap free. It is advisable to work on a soft surface to protect the caseback and bezel. If in doubt, a qualified watchmaker can complete the swap in a matter of minutes.

Yes, the Breitling Avenger A1337111/C871/443X/A20BA.1 uses standard 24mm spring bars, making it compatible with the full range of aftermarket straps in that size. Milano Straps offers a curated selection of handcrafted 24mm straps in premium leathers with customisable finishes, including fully bespoke options through the Casati Milano atelier.

The lifespan of a leather strap depends on the material, frequency of use, and level of care. A quality vegetable-tanned calf strap has an average life of 18 to 36 months with daily wear. Cordovan and vegetable-tanned alligator can exceed five years with proper maintenance — a conditioning cream every two to three months and protection from water. Sweat and salt water are the primary causes of deterioration; in sporting or warm-weather contexts, rotating between multiple straps is strongly advised.
