Strap for Avenger II GMT Stainless Steel / Stratus Silver / Calf / Folding

The lug width of the Breitling Avenger A3239011/G778/438X/A20D.1 is 22mm. This measurement is taken with a digital calliper across the inner distance between the two lugs, not the outer width. Any strap with a 22mm attachment is fully compatible with this reference.

The ideal strap for the Avenger A3239011/G778/438X/A20D.1 depends on intended use. Vegetable-tanned calf leather in cognac or tobacco develops a rich patina over time. Black or dark grey alligator adds formal refinement. Ballistic nylon NATO straps suit intensive use and reinforce the watch's military heritage. Vulcanised rubber is recommended for outdoor or aquatic environments.

Strap replacement requires a spring bar tool to compress and release the spring bars securing the strap to the lugs. Insert the forked tip into the lug slot, compress the spring bar, and slide the strap free. The process does not affect the movement or case and is fully reversible. Work on a soft surface to protect the stainless steel case from scratches.

Yes, any strap with a 22mm lug width is compatible with the Avenger A3239011/G778/438X/A20D.1. The 22mm aftermarket is one of the broadest available. Milano Straps offers a curated selection of handcrafted straps in Tuscan leather, alligator, NATO and rubber, available bespoke or ready to ship, all supplied with spring bars.

Longevity depends on leather quality, frequency of wear, and maintenance. A quality vegetable-tanned calf strap, kept away from prolonged moisture and conditioned periodically, will typically last between three and five years with daily wear. Alligator grain leather, owing to its dense structure, generally offers greater durability. All Milano Straps handcrafted straps carry an 18-month manufacturing warranty.
