Strap for Avenger II GMT Stainless Steel / Mariner Blue / Calf / Pin

The lug width of the Breitling Avenger A3239011/C872/433X/A20BA.1 is 22mm. This measurement is taken with a digital calliper positioned between the two lugs, flush against the case. While 22mm is a relatively common size, it should always be verified before purchasing an aftermarket strap to ensure the spring bar seats correctly and securely.

The ideal choice depends on intended use. For smart-casual daily wear, a vegetable-tanned Tuscan calf leather strap in havana or cognac develops a rich patina that complements the satin-finished steel of the Avenger. For aquatic or high-activity contexts, a high-density rubber strap offers the most practical solution. A heavy-duty NATO strap in bicolour military configurations maintains aesthetic coherence with the model's aeronautical heritage.

Strap removal requires a flat-tip or forked spring bar tool, inserted into the spring bar slot between the lug and the strap end. Compress the spring bar and slide the strap laterally to release it. Always work on a soft surface to prevent case scratches. Replacement spring bars should measure 22mm in span with a standard diameter of 1.8mm to ensure a proper fit.

Yes. The aftermarket offers a broad selection of 22mm straps compatible with this reference. Milano Straps produces handcrafted straps in calf leather, alligator, shell cordovan, and rubber, all available in 22mm lug width and with various closure options including pin buckle and deployant clasp. It is advisable to choose straps with curved ends to match the lug geometry of the Avenger case.

Longevity depends on tanning quality, frequency of wear, and exposure to perspiration and moisture. A high-grade vegetable-tanned leather strap, worn daily and maintained with a light conditioning cream every two to three months and kept away from direct heat, can retain its structural and aesthetic integrity for two to four years. Milano Straps backs its products with an 18-month guarantee against manufacturing defects.
