Strap for Avenger B01 Chronograph 45 Stainless Steel / Blue / Strap - Folding

The lug width of the Breitling Avenger AB01821A1C1X2 is 22mm. This measurement is taken at the lower part of the lugs, where the strap inserts, using a millimetre calliper. It is the critical dimension when selecting a compatible replacement strap.

Given the 45mm case size and the Avenger's instrument-grade character, the most suitable materials are vegetable-tanned calf leather for everyday elegant wear, alligator for formal occasions, technical nylon NATO for aviation-inspired aesthetics, and vulcanised rubber for intensive sport use. All must feature a 22mm lug width.

The strap is removed using a flat-tipped or forked spring bar tool, applying gentle leverage to the spring bar seated within the lugs. To avoid scratching the stainless steel case, it is advisable to protect the lug area with masking tape before proceeding. Spring bars typically have a diameter of 1.8mm.

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Avenger AB01821A1C1X2. Milano Straps offers a curated selection of handcrafted leather, NATO, and rubber straps in 22mm, made from premium materials and covered by an 18-month production warranty.

Longevity depends on material and usage. A quality vegetable-tanned calf strap, maintained with regular conditioning cream, typically lasts 2–4 years. Alligator, owing to its denser hide structure, can exceed 4–5 years. Constant exposure to perspiration, water, and UV radiation significantly reduces strap life; for active use, NATO or rubber is recommended.
