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

The Breitling Avenger A1733110/F563/435X/A20BASA.1 features a lug width of 22mm. This measurement is dictated by the 45mm stainless steel case and is consistent across the large-format Avenger line. To verify the measurement, use a digital calliper to measure the internal distance between the two lugs at the point where the strap inserts.

The ideal strap depends on the intended context. Vegetable-tanned calfskin with a military grain finish is the most versatile option for everyday urban wear. A matte alligator strap elevates the watch in formal settings. Ballistic nylon NATO straps are most faithful to the technical-military identity of the Avenger. Vulcanised rubber is the correct choice for sport or marine use. All straps must be 22mm wide to fit the lugs correctly.

The strap is removed using a spring bar tool inserted into the lateral hole of the lug or directly between the strap and lug. The 22mm spring bars must be compressed laterally to disengage from their seats. The operation takes approximately two minutes and requires no professional equipment, though it is advisable to work on a soft surface to avoid scratching the stainless steel case.

Yes, the aftermarket offers a wide range of compatible straps in 22mm. milanostraps.it offers handcrafted straps in alligator, vegetable-tanned calfskin, NATO nylon, and rubber, all fitted with standard 22mm spring bars compatible with the Avenger lugs. Artisanal construction often provides superior finishing compared to stock options, with full personalisation of colour and texture available.

Longevity depends on the material and usage conditions. A vegetable-tanned calfskin strap, worn daily with proper care — leather conditioner every two to three months, minimal exposure to water — will typically last two to four years while developing a characterful patina. A quality alligator strap can exceed five years of service. Casati Milano artisanal straps carry an 18-month warranty against manufacturing defects.
