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

The lug width of the Breitling Avenger A3239011/BC34/433X/A20BA.1 is 22 mm. This measurement is taken with a digital calliper between the two case lugs and is essential when selecting a compatible aftermarket strap. Any strap with a 22 mm attachment will fit this model without the need for adapters.

The ideal choice depends on intended use. For formal occasions, a black or brown matt alligator strap complements the brushed stainless steel case with authority. For sport or marine use, vulcanised rubber is the most practical option. Vegetable-tanned calfskin in cognac or tobacco offers the greatest versatility, developing a unique patina over time. A ballistic nylon NATO strap remains the most faithful choice to the Avenger's operational character.

Strap replacement is carried out by compressing and removing the spring bars that secure the strap to the case lugs. A dedicated springbar tool or a thin-tipped lever is required. It is advisable to work on a soft surface to protect the case back and lugs. Standard aftermarket straps can be swapped in seconds, while the original steel bracelet is best handled by a qualified watchmaker.

Yes. Any strap with a 22 mm attachment is compatible with this model. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps in 22 mm, manufactured with premium materials and stainless steel buckles of equivalent quality to the original. Standard lengths of 75/115 mm or 75/120 mm accommodate the vast majority of wrist sizes.

A quality leather strap — vegetable-tanned calfskin or Grade A alligator — typically lasts between two and five years with daily wear, depending on exposure to perspiration, water and UV light. Periodic conditioning with a dedicated leather cream and rotating between multiple straps will significantly extend the lifespan of the piece. The Avenger is water-resistant, but it is advisable to remove a leather strap before diving or intensive water activities.
