Strap for Avenger II Seawolf Stainless Steel / Tungsten Gray / Calf / Folding

The lug width of the Breitling Avenger A1733110/F563/436X/A20DSA.1 is 22mm. This measurement is taken internally between the two lugs of the case, perpendicular to the watch's axis, and is essential for selecting a correctly sized aftermarket strap.

For this model with a 45mm stainless steel case and technical character, the most suitable straps are: vegetable-tanned Tuscan calf leather for versatile daily use, matte alligator for formal occasions, ballistic nylon NATO for sporting or outdoor environments, and vulcanised rubber for intensive aquatic use. The choice depends on the intended context and desired colour pairing.

The strap is replaced using a spring bar tool or a flat-head screwdriver. Remove the spring bars connecting the strap to the case lugs, extract the old strap, and insert the new one by snapping the spring bars into position. It is advisable to rest the watch on a soft surface to avoid scratching the case.

Yes. All straps with a 22mm attachment width are compatible with this model. milanostraps.it offers a selection of Italian-crafted straps — in vegetable-tanned leather, alligator, calf, and technical materials — specifically sized for the Avenger's 22mm lugs. It is also important to check the strap thickness at the lug end to ensure a proper fit.

Longevity depends on leather quality, intensity of use, and maintenance. A high-quality vegetable-tanned calf leather strap under moderate daily use typically lasts 18 to 36 months. Frequent exposure to water or perspiration significantly reduces lifespan; in such cases, alternating with a rubber or NATO strap is advisable. Casati Milano straps carry an 18-month warranty against manufacturing defects.
