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

The lug width of the Breitling Avenger A3239011/BC35/435X/A20BA.1 is 22 mm. This measurement is taken internally between the two lugs using a digital calliper positioned perpendicular to the vertical axis of the case. It is the key parameter for selecting any compatible aftermarket strap.

For the 43 mm steel Avenger, the most coherent options are: alligator with hornback grain for formal wear, vegetable-tanned calf leather for daily use with natural patina development, ballistic nylon NATO for consistency with the model's instrumental vocation, and vulcanised rubber for sporting environments. Recommended colour choices include black, navy blue or dark tobacco to maintain harmony with the satin-finished steel case.

To replace the strap, you will need a spring bar tool or a dedicated watch case knife. Insert the tool into the spring bar slot inside the lug, compress the spring extensions and slide the strap outward. Repeat for both lugs. Care should be taken to avoid scratching the case surfaces: it is advisable to protect the case with mylar tape during the operation.

Yes. Any strap with a 22 mm lug width is physically compatible with this model. Milano Straps offers a selection of handcrafted straps in 22 mm, made to proportions consistent with the Avenger's case dimensions, available in various materials and finishes. The original spring bars are generally reusable unless worn.

The lifespan of a leather strap depends on hide quality, tanning method and conditions of use. A mid-grade calf leather strap typically lasts 12–18 months with daily wear. A high-quality alligator or shell cordovan strap can exceed 3–4 years with regular maintenance (conditioning cream every 2–3 months, drying away from direct heat sources). Frequent exposure to perspiration and water significantly reduces leather longevity.
