Strap for Avenger II GMT Stainless Steel / Volcano Black / Rubber / Folding

The lug width of the Breitling Avenger A3239011/BC34/157S/A20D.2 is 22mm. This measurement can be verified directly between the case lugs using a millimetre calliper, and the watch is compatible with any standard 22mm strap, including leather, rubber, NATO and steel bracelet options.

For the Breitling Avenger A3239011/BC34/157S/A20D.2, the most suitable straps are vegetable-tanned calf leather for everyday wear, structured-grain alligator for formal occasions, and vulcanised rubber or ballistic nylon NATO for technical or aquatic environments. The choice depends on the intended context and the desired chromatic pairing with the original black dial.

To replace the strap on the Breitling Avenger A3239011/BC34/157S/A20D.2, a springbar tool is required — a forked instrument used to compress the spring bars housed within the lugs. Insert the tip into the lug hole, compress the spring bar, and slide the strap free. The operation is fully reversible and does not require a watchmaker if carried out with the appropriate tool.

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Avenger A3239011/BC34/157S/A20D.2. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials and finishes, made in Italy, available with a tang buckle or deployant clasp, and specifically designed for sport watches of this calibre.

The lifespan of a leather strap depends on the quality of the tanning process, frequency of wear, and exposure to perspiration and moisture. A quality vegetable-tanned calf leather strap, maintained regularly with conditioning cream, can last between two and five years with daily use. Alligator leather, owing to its dense fibre structure, tends to retain its shape considerably longer. Milano Straps provides an 18-month warranty against manufacturing defects on all straps.
