Strap for Avenger II GMT Stainless Steel / Volcano Black / Military / Pin

The lug width of the Breitling Avenger A3239011/BC34/106W/A20BA.1 is 22mm. This measurement refers to the internal distance between the two lugs of the case, the exact point where the strap is fitted. To verify this on your own piece, it is advisable to use a digital calliper in direct contact with the lugs.

The choice depends on intended use. For an operational, water-resistant profile, a technical nylon NATO or vulcanised rubber strap is most coherent with the model's DNA. For everyday smart-casual wear, a 22mm vegetable-tanned calf leather strap with a brushed steel buckle or deployant clasp pairs well with the satin-finished case. Alligator leather is reserved for formal contexts or for those seeking the finest grain and long-term patina development.

Strap replacement requires a spring bar tool to compress the spring bars securing the strap to the lugs. Insert the tip into the lateral notch of the lug, compress the spring bar and slide the strap free. The operation is reversible and requires no specialist tools beyond the spring bar tool; however, to avoid scratching the case, it is advisable to protect adjacent surfaces with low-tack masking tape.

Yes. Any strap with a 22mm attachment and standard length (approximately 75mm + 115mm or 70mm + 120mm) is compatible. Milano Straps offers an artisanal selection in leather, NATO and rubber specifically sized for the 22mm lug width of this Avenger, with options for customising the buckle and keeper in steel, black PVD or rose gold to match the original case finish.

Longevity depends on leather type, frequency of use and exposure to perspiration and moisture. A quality vegetable-tanned calf leather strap used daily under moderate conditions will retain its structural and aesthetic integrity for 18 to 36 months. Alligator, owing to the natural structure of its scales, is more resistant to surface moisture and can last over three years with routine maintenance. Immersion should be avoided, and the leather should be conditioned with an unscented cream every two to three months.
