Strap for Avenger II Seawolf Stainless Steel / Cobra Yellow / Calf / Pin

The lug width of the Breitling Avenger A1733110/I519/433X/A20BASA.1 is 22mm. This measurement is standard across the 45mm Avenger family and allows fitment of any aftermarket strap with a 22mm attachment, whether using fixed spring bars or a quick-release system.

The ideal choice depends on intended use. For a refined look, alligator leather or shell cordovan complement the 45mm case with a distinguished texture. For sport or aquatic use, an FKM or vulcanised rubber strap is most consistent with the watch's 300-metre water resistance rating. A premium NATO nylon strap delivers an authentic aviator aesthetic true to the Avenger's heritage.

Strap replacement requires a spring bar tool, readily available online or from any watchmaker. Insert the tool tip into the lug hole, compress the spring bar and slide the strap free laterally. Take care not to scratch the steel lugs — protect the case with a soft cloth during the operation. The procedure is straightforward and takes no more than a few minutes.

Yes — any strap with a 22mm attachment is compatible with the Breitling Avenger A1733110/I519/433X/A20BASA.1. Milanostraps.it offers an extensive range of handcrafted 22mm straps in various materials — leather, alligator, shell cordovan, rubber and NATO — all produced to sartorial standards and fully compatible with this model's technical specifications.

Longevity depends on leather quality, tanning method and daily use. A high-quality vegetable-tanned calf strap, with regular use and proper maintenance (conditioning cream every 2–3 months, avoiding prolonged water exposure), typically lasts 2–4 years. Shell cordovan, owing to its dense grain structure, is considerably more durable and can last upwards of 5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
