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

The lug width of the Breitling Avenger A1733110/BC31/200S/A20DSA.2 is 22mm. This measurement refers to the internal distance between the two lugs of the case, determining the correct strap width to purchase. To verify this on your own watch, use a digital calliper positioned between the lugs flush against the crystal.

The ideal choice depends on intended use. For formal or smart-casual occasions, a flat-belly alligator strap with vegetable tanning complements the instrument character without compromising it. For everyday or sporting use, a ballistic nylon NATO or vulcanised rubber strap provides durability and moisture resistance. Full-grain calfskin with vegetable tanning remains the most versatile option, developing a distinctive patina over time.

Strap replacement requires a double-pronged spring bar tool (0.8mm tip). Insert the tool into the groove between the lug and the strap keeper, compress the spring bar inward and slide the strap free. Care should be taken to avoid scratching the steel lugs; masking tape applied around the lug area is recommended as a precaution during the operation.

Yes. Any strap with a 22mm lug width and standard 22mm spring bars is compatible. Milano Straps offers a curated selection of handcrafted Italian straps in various taper widths (20mm or 22mm at the buckle), available with a pin buckle or deployant clasp. Both online ordering and bespoke commissions through Casati Milano are available.

Longevity depends on leather quality, frequency of wear and exposure to perspiration and moisture. A quality vegetable-tanned calfskin strap, rotated with other straps and properly maintained, can last between two and five years. Alligator, when conditioned regularly with a colourless leather cream, typically outlasts calfskin. Direct water immersion should be avoided with untreated leathers, and straps should be stored away from direct heat sources.
