Strap for Avenger II GMT Stainless Steel / Mariner Blue / Rubber / Folding

The lug width of the Breitling Avenger A3239011/C872/153S/A20D.2 is 22mm. This is the standard measurement for the 43mm Avenger case and is compatible with all 22mm straps in the Milano Straps catalogue, requiring no adapters or modifications.

The ideal strap for the Breitling Avenger A3239011/C872/153S/A20D.2 depends on intended use. For sport or field wear, a ballistic nylon NATO or vulcanised rubber strap offers durability and moisture resistance. For a more formal setting, a Hornback alligator strap in midnight black or navy blue complements the satin-brushed steel case. Vegetable-tanned calfskin strikes the right balance for everyday versatile wear.

To replace the strap on the Breitling Avenger A3239011/C872/153S/A20D.2, you will need a spring bar tool. The Avenger lugs accept standard 22mm spring bars. Insert the tip of the tool into the side hole of the lug or into the spring bar groove, compress the spring, and slide the strap free. The process takes approximately two minutes and requires no professional tools, though working on a soft surface is advised to prevent scratching the case.

Yes, all aftermarket straps with a 22mm attachment width are compatible with the Breitling Avenger A3239011/C872/153S/A20D.2. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps made specifically for 22mm lugs, with reinforced stitching and stainless steel spring bars included. Build quality is comparable to or exceeds that of original Breitling accessories, with full customisation options available.

The lifespan of a leather strap depends on the material, maintenance and frequency of use. A quality vegetable-tanned calfskin strap, regularly conditioned and kept away from prolonged moisture exposure, will typically last between two and four years with daily wear. Alligator leather, owing to its dense scale structure, tends to last longer provided it is not subjected to heavy perspiration or water immersion. Milano Straps provides an 18-month warranty against manufacturing defects on all straps in the catalogue.
