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

The lug width of the Breitling Avenger A1733110/BC31/434X/A20DSA.1 is 22 mm. This measurement should be taken with a digital calliper, measuring the internal distance between the two lugs at the point where the strap meets the case. Adhering to this specification is essential for a secure fit and correct aesthetic alignment.

For this 45 mm stainless steel Avenger, the most suitable materials are vegetable-tanned Tuscan calf leather for an authentic, lived-in appearance, hornback alligator for formal occasions, ballistic nylon NATO for sporting use, and vulcanised rubber for aquatic environments. A steel deployant clasp is recommended to maintain visual coherence with the case.

Strap replacement requires a spring bar tool. Insert the forked tip into the lug slot, compress the spring bar, and slide the strap free. Care should be taken to avoid scratching the stainless steel lugs. For a professional result, it is advisable to rely on a watchmaker or contact Milano Straps directly for an assisted fitting service.

The lifespan of a leather strap depends on frequency of use, exposure to perspiration and moisture, and the quality of the tanning process. A high-quality vegetable-tanned calf strap worn daily with proper care will typically last 2–4 years. Alligator and shell cordovan, owing to their denser fibre structure, tend to last considerably longer. Avoiding prolonged water exposure significantly extends the strap's service life.
