Strap for Avenger II Seawolf Stainless Steel / Volcano Black / Calf / Folding

The lug width of the Breitling Avenger A1733110/BC30/438X/A20DSA.1 is 22mm, measured internally between the case lugs. This is the standard size across the 45mm Avenger family and ensures a wide availability of compatible aftermarket straps.

This model pairs well with vegetable-tanned calfskin for daily wear, Louisiana alligator for formal occasions, ballistic nylon NATO for aviation or sport use, and vulcanised rubber for marine environments. A brushed steel buckle or deployant clasp coordinates naturally with the case finishing.

The strap is replaced by removing the spring bars from the lugs using a fine-tipped spring bar tool. Given the large 45mm case with prominent lugs, a double-lever tool is recommended to avoid scratching the brushed steel. No case opening or watchmaking expertise is required.

Yes. Any standard 22mm strap is compatible. Milano Straps offers a selection of handcrafted 22mm straps specifically tested on large-diameter cases such as this, available in leather, NATO and rubber, including versions with a deployant clasp.

A quality vegetable-tanned calfskin strap worn daily on an active wrist has an estimated lifespan of 18 to 36 months before replacement becomes aesthetically advisable. Alligator leather tends to last longer due to its denser fibre structure. Minimising exposure to water and acidic perspiration significantly extends the leather's service life.
