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

The lug width of the Breitling Avenger A1338111/C870/105X/A20BA.1 is 22mm. This measurement is taken with callipers directly between the lugs on the inner surface where the strap inserts. Adhering to this specification is essential for a correct fit and to avoid lateral play between the strap and the case.

The choice depends on intended use. For formal occasions, a vegetable-tanned alligator strap in 22mm enhances the stainless steel case and develops a distinctive patina over time. For intensive daily or sports use, cross-grain calf leather or a technical nylon NATO offer durability and stability. A satin-finished steel deployant clasp is the recommended closure for even pressure distribution across the wrist.

The strap is removed using a flat-tipped spring bar tool or a dedicated watch screwdriver. The spring bars retaining the strap are compressed laterally by applying gentle leverage against the inner profile of the lug. It is advisable to work on a soft surface to avoid scratching the case. If in doubt, entrust the operation to a watchmaker or specialist atelier.

Yes. Any strap with a 22mm lug width is technically compatible, provided the spring bars are of the correct diameter and the strap ends conform to the lug geometry. Milano Straps offers a curated selection of handcrafted 22mm straps — in leather, NATO, and rubber — engineered specifically for watches of this size and weight.

Longevity depends on leather quality and frequency of use. A handcrafted alligator or vegetable-tanned calf strap worn daily in moderate conditions will retain structural and aesthetic integrity for 2 to 4 years. Prolonged exposure to perspiration, water, and UV radiation accelerates deterioration. Rotating between at least two straps and occasionally applying a neutral leather conditioner will extend service life considerably.
