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

The lug width of the Breitling Avenger A3239011/G778/112X/A20D.1 is 22mm. This measurement should be taken with a calliper between the inner terminals of the case and is the key parameter for selecting a compatible strap. A 22mm strap ensures a precise fit and correct proportions against the 43mm case diameter.

The ideal strap for the Avenger A3239011/G778/112X/A20D.1 depends on intended use. For an elegant instrumental look, a semi-matte alligator strap in black or burnt brown paired with a steel deployant clasp is the most refined option. For sports or everyday wear, a vegetable-tanned calfskin or technical nylon NATO strap reinforces the model's aeronautical character while offering durability and practicality.

Replacing the strap on the Avenger requires a spring bar tool with a fine tip. Insert the tip into the lug notch and compress the spring bar to release the strap from its seat. Exercise caution to avoid scratching the stainless steel case: covering the bezel with protective tape before proceeding is advisable.

Yes, any standard 22mm strap is compatible with the Avenger A3239011/G778/112X/A20D.1, provided the end piece is straight or features a moderate curve suited to the case profile. Milano Straps offers a curated selection of handcrafted leather, rubber and fabric straps in 22mm, produced with premium materials and hand-stitched saddle seams, at a fraction of authorised dealer prices.

The longevity of a leather strap depends on hide quality, tanning method and daily wear conditions. A quality vegetable-tanned calfskin strap, with regular conditioning (leather cream every 2–3 months) and protection from direct water exposure, retains structural and aesthetic integrity for 2–4 years under daily use. A hand-finished alligator strap of the highest grade can exceed 5 years while retaining its patina and suppleness.
