Strap for Avenger II Seawolf Stainless Steel / Tungsten Gray / Military / Pin

The lug width of the Breitling Avenger A1733110/F563/109W/A20BASA.1 is 22mm. This measurement refers to the internal distance between the two spring bar attachment points and can be verified using a digital calliper or Breitling's official technical documentation.

For the 45mm case of the Avenger, the most suitable straps are a technical nylon NATO for sporting use, a vegetable-tanned calf leather strap for daily wear, and a hornback alligator strap for more formal occasions. All options must feature a 22mm lug width to ensure a correct and secure fit.

To replace the strap, use a dedicated spring bar tool to compress and release each spring bar from the lug channel. Apply gentle lateral pressure at the lug opening, releasing one side first and then the other. It is advisable to work on a soft surface to avoid scratching the stainless steel case.

Yes, any strap with a 22mm lug width is technically compatible with this reference. Milano Straps offers a curated selection of handcrafted leather, nylon and rubber straps made specifically for 22mm lugs, with stainless steel buckles and deployant clasps proportioned to suit the Avenger's 45mm case.

Longevity depends on leather type, frequency of use and maintenance. A quality vegetable-tanned calf leather strap worn daily typically lasts 2–4 years with proper care. Alligator leather, owing to its dense fibre structure, can exceed 5 years when maintained correctly. Prolonged exposure to water and perspiration will significantly reduce the lifespan of any leather strap.
