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

The lug width of the Breitling Avenger A1733110/I519/437X/A20BASA.1 is 22mm. This measurement refers to the internal distance between the two case lugs at the strap attachment point and determines compatibility with any aftermarket or original strap.

For a 45mm tool watch such as this Avenger, the most suitable materials are bombé-grain alligator leather for a refined pairing, vegetable-tanned Tuscan calf leather for intensive daily wear (it develops an authentic patina over time), vulcanised rubber for sporting contexts, and ballistic nylon NATO for the closest adherence to the watch's aeronautical vocation.

Strap replacement requires a spring bar tool: insert the tip into the slot between the lug and the spring bar, compress the bar and slide it out. The operation should be carried out carefully to avoid scratching the stainless steel case. It is advisable to use a watch cushion and a nylon or brass tip to protect polished surfaces.

Yes. Any standard 22mm strap is compatible with this model. On milanostraps.it, a wide range of handcrafted straps in leather, alligator, calf, rubber and NATO are available, specifically selected for the 22mm lug width, with customisable finishes and stitching also available through the Casati Milano bespoke service.

A quality leather strap — made from vegetable-tanned hide with saddle stitching — can last between 2 and 5 years with daily use, depending on exposure to perspiration, water and heat. Regular conditioning with a natural-based leather cream significantly extends the strap's lifespan. For environments with frequent water exposure, vulcanised rubber or a technical NATO strap is recommended.
