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

The lug width of the Breitling Avenger A1733110/F563/433X/A20BASA.1 is 22mm. This measurement must be taken internally between the two lugs using a calliper placed directly against the case, to ensure accurate compatibility with any replacement strap.

For a 45mm stainless steel case such as the Avenger's, the most suitable materials are wide-grain alligator (dark brown or tobacco), vegetable-tanned calfskin for those who appreciate developing patina over time, ballistic nylon NATO straps for a military aesthetic, and vulcanised rubber for sporting or marine environments. The ideal choice depends on the wearer's primary use case and preferred colour pairing.

Strap replacement requires a fine-tipped spring bar tool. Insert the tip into the dedicated notch on the spring bar, compress the spring and slide the strap free from the lug. The operation is non-invasive and does not require specialist watchmaking skills, though working on a soft surface is advisable to protect the case from scratches. Original 22mm spring bars are reusable provided they are not deformed.

Yes. Any strap with a 22mm lug width is technically compatible with the Avenger A1733110/F563/433X/A20BASA.1. Milano Straps offers a curated selection of handcrafted straps in leather, alligator, NATO and rubber, specifically proportioned to complement the substantial presence of a 45mm case.

The lifespan of a leather strap depends on tanning quality, exposure to perspiration and moisture, and periodic maintenance. A quality vegetable-tanned strap, conditioned with leather cream every three to four months and kept away from prolonged water exposure, can last between three and seven years whilst retaining structural integrity. Intensive sporting use will significantly reduce this estimate; in such cases, alternating with a rubber or NATO strap is advisable.
