Strap for Avenger II Seawolf Stainless Steel / Tungsten Gray / Calf / Folding

The lug width of the Breitling Avenger A1733110/F563/438X/A20DSA.1 is 22mm. This measurement is taken with a calliper between the two case lugs at the strap attachment point. It is the standard dimension for large-format tool watches and ensures a wide availability of compatible aftermarket straps.

For a 45mm stainless steel case with a military-oriented design, the most coherent strap options are: alligator belly leather in black or brown for formal settings, vegetable-tanned calf leather for daily wear with natural patina development, and technical nylon NATO straps for maximum durability and practicality. The strap must be 22mm wide to ensure a proper fit between the lugs.

To replace the strap, use a fine-tipped spring bar tool. Insert the tip into the slot on the inner side of the lug, compress the spring bar, and slide the strap out. Take care not to scratch the stainless steel lugs. Insert the new 22mm strap by hooking one end of the spring bar first, then compressing the other end to secure it into the second lug.

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Avenger A1733110/F563/438X/A20DSA.1, provided the spring bars have the correct diameter (standard 1.5mm) and the total strap length (typically 75mm+115mm for a 45mm case) suits the wearer's wrist circumference. Milano Straps offers a dedicated selection of handcrafted 22mm straps.

A quality leather strap — vegetable-tanned calf or alligator — typically lasts between 18 and 36 months with intensive daily wear, depending on exposure to perspiration, water, and UV light. Vegetable-tanned leather develops a distinctive patina over time but is sensitive to prolonged moisture. For sport or outdoor use, a rubber or technical NATO strap is recommended. Rotating between multiple straps significantly extends the service life of each one.
