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

The lug width of the Breitling Avenger A3239011/BC34/109W/A20BA.1 is 22 mm. This measurement is standard across the entire 43 mm Avenger family and ensures broad compatibility with a wide range of quality aftermarket straps.

The ideal choice depends on the intended use. For an aesthetic consistent with the tool watch character, a ballistic nylon NATO or a vulcanised rubber strap are technically sound options. For smarter or urban wear, a vegetable-tanned calf leather strap with a matte finish or a bombé alligator in anthracite tones enhances the 43 mm case without compromising its nature.

Strap replacement requires a flat-tip or fork-style spring bar tool, available in any basic watchmaker's kit. Insert the tool into the lug channel, compress the spring bar and slide the strap free. The operation takes approximately 2–3 minutes for a first-time user. If in doubt, it is advisable to consult a watchmaker or a specialist atelier such as Casati Milano.

Yes. The 22 mm lug width is one of the most common measurements in the high-end tool watch segment, and the aftermarket offers a broad selection of quality options. Milanostraps.it provides handcrafted leather, NATO and rubber straps made from carefully selected materials, all compatible with the 22 mm lugs of the Breitling Avenger.

Longevity depends on leather quality, frequency of wear and exposure to perspiration and moisture. A quality vegetable-tanned calf strap, maintained with a regular application of leather conditioner, will retain its structural integrity for 2–4 years of daily wear. Alligator, owing to its dense grain structure, can last over 5 years if kept away from moisture. For intensive or active use, vulcanised rubber is recommended as it withstands atmospheric agents without degradation.
