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

The lug width of the Breitling Avenger A3239011/BC35/105X/A20BA.1 is 22mm. This measurement is taken between the inner surfaces of the lugs at the strap insertion point and determines compatibility with any aftermarket strap of the same width.

For this 43mm steel Avenger, the most suitable materials are vegetable-tanned calf leather for everyday wear, hornback alligator for formal occasions, vulcanised rubber for wet environments, and ballistic nylon NATO for fidelity to the watch's military origins. The ideal choice depends on intended use and preferred colour pairing.

Strap replacement requires a fine-tipped spring bar tool: compress the spring bar on the inner lug side, slide out the original strap and fit the new one, ensuring both spring bars click securely into the lug holes. The process is fully reversible in under two minutes without risk of scratching the case when the correct tool is used.

Yes. Any strap with a standard 22mm lug width is compatible. MilanoStraps offers a curated selection of Italian handcrafted straps specifically sized for the Avenger, with length and thickness optimised for the model's robust lugs, available in leather, rubber and textile.

The lifespan of a leather strap depends on leather quality, frequency of use and exposure to perspiration and moisture. A quality calf strap typically lasts 18 to 36 months with daily wear; a vegetable-tanned alligator strap can exceed five years with proper care. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
