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

The lug width of the Breitling Avenger A1733110/BC31/433X/A20BASA.1 is 22mm. This measurement is taken internally between the two lugs at the lower part of the case and is the key parameter for selecting a compatible strap. All 22mm straps in the MilanoStraps catalogue are dimensionally verified for compatibility with this reference.

The ideal choice depends on context. For formal or business wear, an alligator belly or vegetable-tanned calf leather strap best complements the 45mm stainless steel case. For sport or marine use, vulcanised rubber offers full water resistance and comfort. A 22mm ballistic NATO strap remains the most authentic choice given the Avenger's original military brief.

The strap is removed using a spring bar tool or a dedicated lug lever, compressing the spring bars inward until they release from the lug holes. It is advisable to place the watch on a soft cushion to protect the case during the process. The original 22mm spring bars may be reused with the new strap, provided they are in sound condition and the correct length for these lugs.

Yes. Any standard 22mm strap with correctly sized spring bars (typically 1.8mm in diameter) is compatible with the Breitling Avenger A1733110/BC31/433X/A20BASA.1. MilanoStraps offers a curated selection of handcrafted 22mm straps in leather, NATO and rubber, each dimensionally checked for compatibility with the lug geometry of this model.

Longevity depends on the material and frequency of wear. A quality vegetable-tanned calf strap worn daily can last between 18 and 36 months before showing significant wear at the buckle holes and keeper. Prolonged exposure to moisture or water will reduce this estimate considerably. MilanoStraps straps carry an 18-month warranty against manufacturing defects; wear from regular use is considered normal and is not covered.
