Strap for Avenger II Seawolf Stainless Steel / Volcano Black / Rubber / Folding

The lug width of the Breitling Avenger A1733110/BC31/157S/A20DSA.2 is 22 mm, measured horizontally between the two upper lugs of the case. This is a specific dimension of the 45 mm Avenger family and must be respected precisely to ensure correct attachment and balanced aesthetics.

For a 45 mm Avenger, the choice depends on intended use. Flat-belly alligator in vegetable-tanned leather suits formal contexts, naturally patinated calfskin is ideal for elegant daily wear, ballistic nylon NATO for sporting use, and vulcanised rubber for operational or aquatic environments. In all cases, the attachment width must be 22 mm.

To replace the strap, use a spring bar tool with a fine or forked tip. Insert the tool into the slot between the lug and the strap end, compress the spring bar and slide the strap free. Repeat on the opposite lug. Fit the new strap by seating the pre-loaded spring bar on one lug first, then compressing the opposite end until it clicks into place. The operation takes approximately two minutes.

Yes. Any strap with a 22 mm attachment width and straight or compatible end pieces fitting the Avenger lug geometry is technically mountable. Milanostraps.it offers a curated selection of handcrafted 22 mm straps in leather, rubber and nylon, each selected for compatibility with this reference, with steel buckle or deployant clasp options.

Longevity depends on leather type, frequency of use and exposure to perspiration and moisture. A quality vegetable-tanned calfskin strap worn daily typically lasts 18 to 24 months. Well-maintained alligator can exceed three years. For sport watches in intensive use, rotating between multiple straps or opting for vulcanised rubber in demanding conditions is strongly recommended.
