Frequently asked questions

What is the lug width of the Breitling Avenger A17331101I1S1?

The Breitling Avenger A17331101I1S1 features a lug width of 22mm. This measurement is standard across the 45mm Avenger generation and determines compatibility with all 22mm aftermarket straps, including NATO, leather and rubber variants.

What is the best strap for the Breitling Avenger A17331101I1S1?

The most suitable straps for the Avenger A17331101I1S1 are: a premium ballistic nylon NATO for sporting or operational use, vegetable-tanned fine-grain calf leather for refined everyday wear, matte alligator for formal occasions, and vulcanised rubber for aquatic or high-intensity activities. A brushed steel deployant clasp completes any combination with functional elegance.

How do you change the strap on a Breitling Avenger A17331101I1S1?

Strap replacement requires a fine-tip spring bar tool. Insert the tool into the gap between the lug and the strap's spring bar, compress the spring and slide the strap free. Care should be taken to avoid scratching the satin-finished case surfaces. It is advisable to rest the watch face-down on a soft cloth throughout the process.

Are there aftermarket straps compatible with the Breitling Avenger A17331101I1S1?

Yes, any strap with a 22mm attachment width is technically compatible with the Avenger A17331101I1S1. Milano Straps and Casati Milano produce bespoke handcrafted straps in various leathers and materials, with buckle or deployant fastening, offering dimensional compatibility and a level of craftsmanship that surpasses the standard factory strap.

How long does a leather strap last on a Breitling Avenger A17331101I1S1?

The lifespan of a leather strap depends on material quality and usage habits. A handcrafted vegetable-tanned calf leather strap typically lasts 2 to 4 years with daily wear. Alligator straps, owing to the inherent density of the hide, can exceed 5 years when kept away from prolonged exposure to moisture and perspiration. Casati Milano provides an 18-month warranty against manufacturing defects.
