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

The lug width of the Breitling Avenger A1733110/F563/106W/A20BASA.1 is 22mm. This dimension is inherent to the 45mm case design and determines compatibility with any aftermarket strap. It is advisable to verify the measurement using a millimetre calliper, measuring the internal gap between the two lugs before purchasing a replacement strap.

For a 45mm case such as the Avenger's, the most suitable straps are those that match the visual weight of the instrument. Semi-matte alligator leather with contrast stitching is the most refined option, whilst vegetable-tanned calf leather develops a distinctive patina over time and offers excellent versatility. For sport use or humid environments, vulcanised rubber provides waterproofing and grip. A ballistic nylon NATO strap remains truest to the model's military heritage.

Replacing the strap requires a spring bar tool — either a flat-tip or forked lever type — available from any watchmaker's supply kit. Insert the tip into the spring bar slot on the lug, compress the spring and slide the strap free. The operation requires no specialist technical knowledge but should be carried out on a soft cloth to prevent case scratching. Standard 1.5mm diameter spring bars are compatible with 22mm lugs.

Yes, any strap with a 22mm attachment width is compatible with the Breitling Avenger A1733110/F563/106W/A20BASA.1. This is a widely available size with extensive aftermarket coverage. Milanostraps.it stocks handcrafted straps in various materials — leather, alligator, rubber and NATO — all produced in 22mm width, available in standard lengths or made-to-measure for different wrist circumferences.

The lifespan of a leather strap depends on material quality, tanning method and conditions of use. A vegetable-tanned calf leather strap, properly maintained and not routinely exposed to water, typically lasts 2 to 4 years with daily wear. High-quality alligator can last 4 to 6 years when protected from abrasion and prolonged moisture. Milano Straps guarantees all handcrafted straps for 18 months against manufacturing defects.
