Strap for Avenger II Seawolf Black Steel / Blue MOP / Rubber

The lug width of the Breitling Avenger M17331AT.BE95.134S is 22mm. This is the standard measurement for the 45mm Avenger case and should be confirmed with a digital calliper measuring the internal distance between the two lugs before purchasing an aftermarket strap.

The ideal choice depends on intended use. For sports or operational environments, a vulcanised rubber strap or a 22mm ballistic nylon NATO strap offer the best durability. For business or formal wear, a vegetable-tanned Tuscan calf strap in dark brown or an alligator Belly strap with contrast stitching provide a proportionate match for the 45mm case.

You will need a fine-tipped or forked spring bar tool. Insert the tool into the lug hole to compress the spring bar, then slide the strap free. Reverse the process to fit the new strap, ensuring the spring bar is fully seated. On Breitling cases with guarded lugs, work on a soft cushion to avoid scratching the brushed surfaces.

Yes. Any 22mm strap with end pieces of appropriate thickness for the Breitling Avenger lug depth is compatible. Milanostraps.it offers a curated range of handcrafted 22mm straps in leather, rubber and textile, with shaped ends designed to follow the lug curvature typical of large-diameter tool watches.

Longevity depends on material, usage and care. A vegetable-tanned Tuscan calf strap worn daily in non-sporting contexts typically lasts 2 to 4 years before structural wear appears at the buckle end. Alligator, when kept away from water and perspiration, can exceed 5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
