Strap for Avenger II GMT Stainless Steel / MOP / Japan Special Edition

The Breitling Avenger A3239011/A809/170A features a 22mm lug width. This measurement refers to the internal distance between the two lugs of the case and is the critical parameter for selecting a correctly fitting aftermarket strap with no lateral play.

The ideal choice depends on the intended use. For formal occasions, a hand-stitched alligator or vegetable-tanned calf leather strap paired with a brushed steel buckle or deployant clasp complements the instrument's stature. For sport or tactical use, a 22mm ballistic nylon NATO or vulcanised rubber strap provides durability and tool-free quick-change capability. The 22mm lug width is well-served by the quality aftermarket.

Strap replacement requires a spring bar tool — either a flat-blade variant or a dedicated lug tool — to compress the spring bars seated within the lugs. Release one side at a time, slide out the bar, remove the strap, and reverse the procedure with the new one. The operation takes a few minutes with the correct tool; alternatively, any watchmaker or specialist atelier can carry it out without removing the movement.

Yes. Any strap with a 22mm attachment width is mechanically compatible with this Breitling reference. Milanostraps.it offers a curated range of handcrafted 22mm straps in leather, alligator, NATO and rubber, also available in bespoke configurations through the Casati Milano atelier.

Longevity depends on the hide, tanning method and frequency of use. A quality vegetable-tanned calf leather strap used daily typically lasts between 18 and 36 months before requiring replacement. Alligator leather, being more compact and less porous, generally outlasts calf leather when kept away from sustained moisture exposure. Avoiding prolonged contact with water, perspiration and solvents significantly extends service life.
