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

The lug width of the Breitling Avenger A1337111/C871/444X/A20D.1 is 24mm. This is one of the widest lug sizes found on production wristwatches, consistent with the 48mm case diameter. To verify it independently, measure the internal distance between the two lugs at the strap attachment point using a digital calliper.

For a 48mm Avenger, the most appropriate materials are belly-cut alligator in black or tobacco brown — for its three-dimensional grain that complements the brushed steel finishing — shell cordovan for those seeking durability and long-term patina development, and vulcanised rubber for aquatic or high-intensity environments. A steel deployant clasp ensures aesthetic coherence with the case.

The strap is removed using a spring bar tool: insert the forked tip into the notch on the lug, compress the spring bar and slide the strap free. For a 48mm Avenger, spring bars should be robust — preferably 1.5mm diameter — to bear the weight of the case properly. If in doubt, consult a qualified watchmaker.

Yes. Any strap with a 24mm lug width is technically compatible with the Breitling Avenger A1337111/C871/444X/A20D.1. Milanostraps.it offers a dedicated selection of 24mm straps in various materials and finishes, available for immediate dispatch or made to order through the Casati Milano atelier.

Longevity depends on material and usage. A quality alligator or shell cordovan strap, tanned using vegetable processes, can last between three and seven years with regular maintenance — biannual conditioning and prompt drying after moisture exposure. The mass of a 48mm case places significant stress on the fold area; quality spring bars and a sturdy keeper are essential for even load distribution.
