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

The lug width of the Breitling Avenger A3239011/BC34/435X/A20BA.1 is 22 mm. This measurement is standard across the Avenger GMT line with a 43 mm case and defines the compatible strap width at the point of attachment to the case.

For the Breitling Avenger GMT 22mm, the most suitable options are a matte alligator belly strap for formal settings, vegetable-tanned calfskin for everyday versatility, and ballistic nylon NATO or vulcanised rubber for sporting and field use. The ideal choice depends on the intended context and the desired chromatic pairing with the dial.

To replace the strap on a Breitling Avenger 43mm, a spring bar tool with a fine tip is required. By applying lateral pressure to the spring bar housed within the lug, the bar compresses and the strap can be removed. Whilst the procedure does not require specialist tools, it is advisable to consult a watchmaker or authorised retailer to avoid scratching the stainless steel case.

Yes, any strap with a 22 mm lug width is technically compatible with the Breitling Avenger A3239011/BC34/435X/A20BA.1. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials — leather, alligator, NATO, rubber — fitted with standard spring bars compatible with genuine Breitling lugs.

The lifespan of a leather strap on a Breitling Avenger depends on the material and frequency of use. A quality vegetable-tanned calfskin strap, worn daily with moderate exposure, typically lasts between 18 and 36 months before showing significant wear at the keeper loop. A high-quality alligator strap can exceed 4 to 5 years of use. Milano Straps provides an 18-month warranty against manufacturing defects on all handcrafted straps.
