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

The lug width of the Breitling Avenger A1337111/C871/105W/A20BA.1 is precisely 24mm, measured perpendicularly from lug to lug. This dimension is characteristic of larger Avenger models and is critical to verify when purchasing an aftermarket strap to ensure perfect compatibility.

For the 48mm Avenger, full-grain alligator leather is the most appropriate choice, as its natural texture resists abrasion and develops a distinctive patina reflecting actual use. Vegetable-tanned calf offers initial suppleness and elegant ageing, whilst military-grade NATO cordura maximises operational practicality without aesthetic compromise.

To change the strap, use a dedicated spring bar tool. Position the flat end under the helical spring that supports the strap pin, applying gentle pressure to compress the spring and slide the pin out from the lug. Repeat on the opposite side. Insert the new strap by aligning the holes with the pins, then slide the pin through until you hear the engagement click.

Yes, any strap with a 24mm lug width is mechanically compatible with the Avenger A1337111/C871/105W/A20BA.1. However, it is strongly recommended to choose artisan-crafted straps of superior quality—full-grain alligator, vegetable-tanned calf, or structured canvas—manufactured by specialised ateliers such as Casati Milano, to ensure longevity and aesthetic coherence with the instrument.

A premium leather strap (alligator or vegetable-tanned calf) typically lasts 4-6 years with moderate daily use, though the greater weight of a 48mm case accelerates mechanical wear. With careful maintenance (regular drying after moisture exposure, avoidance of extreme folding), lifespan can extend to 8 years. NATO or reinforced canvas straps have potentially indefinite durability if properly maintained.
