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

The lug width of the Breitling Avenger A1733110/F563/437X/A20BASA.1 is 22mm. This measurement is taken between the two lugs of the 45mm stainless steel case and determines compatibility with any standard 22mm aftermarket strap.

For the 45mm steel Avenger, a vegetable-tanned calf leather strap in tobacco brown or black offers the best aesthetic coherence with the tool-watch character of the model. Alligator leather introduces a formal contrast, while vulcanised rubber is preferable for sporting use or humid environments. The lug width to observe is 22mm.

To replace the strap on the Avenger, use a spring bar tool or a fine-tipped lug removal lever. Standard spring bars are released by compressing their ends towards the centre of the lug. It is advisable to work on a soft surface to avoid scratching the bezel or case. If an integrated bracelet is fitted, replacement may require dedicated tools or the assistance of a qualified watchmaker.

Yes. Any strap with a 22mm lug width is compatible with the Breitling Avenger A1733110/F563/437X/A20BASA.1. Milano Straps offers a curated selection of handcrafted 22mm straps in leather, alligator, rubber and NATO, all available with selectable finishes and stitching. Compatibility is guaranteed by the standard spring bar lug size.

The lifespan of a leather strap depends on the quality of the hide and the level of care applied. A handcrafted vegetable-tanned calf leather strap, worn daily, typically lasts between 18 and 36 months. Alligator leather, thanks to its denser fibre structure, generally has a longer service life. Prolonged exposure to perspiration, moisture and UV radiation accelerates degradation; applying a neutral leather conditioner every two to three months will significantly extend the strap's life.
