Strap for Super Avenger II Stainless Steel / Volcano Black / Calf / Pin

The lug width of the Breitling Avenger A1337111/BC29/101X/A20BA.1 is 24mm. This measurement, proportioned to the 48mm case, is essential for ensuring a precise fit and correct visual continuity between the strap and the case. Before purchasing an aftermarket strap, it is advisable to verify the measurement using a digital calliper by measuring the internal distance between the lugs.

For the 48mm Avenger, the most suitable materials are vulcanised rubber — consistent with the watch's operational character and fully waterproof — and ballistic nylon NATO for those who favour the military aesthetic. Those seeking a more formal pairing may opt for a wide-grain alligator strap in matte black or chocolate brown, which creates a compelling material contrast against the brushed steel case.

The strap is removed using a double-pronged spring bar tool to extract the 24mm spring bars housed within the case lugs. Care should be taken to avoid scratching the case finish: it is recommended to protect the lugs with PTFE tape or to entrust the operation to a qualified watchmaker for the first few changes. The original spring bars can be reused if they remain in good condition.

Yes, any strap with a 24mm lug width is technically compatible with the Breitling Avenger A1337111/BC29/101X/A20BA.1. Milano Straps offers a selection of handcrafted straps in 24mm across various materials — leather, rubber, NATO — fitted with standard 1.8mm diameter spring bars. For a bespoke solution with direct leather selection, Casati Milano offers a made-to-order service with an 18-month guarantee.

Longevity depends on the material and intensity of use. A quality vegetable-tanned calf strap, with moderate daily wear, typically lasts 18 to 36 months before showing significant wear at the holes. An alligator strap, thanks to the structural properties of exotic leather, can last 3 to 5 years whilst retaining its aesthetic and structural integrity. For a 48mm watch used in sporting or humid environments, rubber or NATO straps remain the most durable long-term choices.
