Frequently asked questions

What is the lug width of the Breitling Avenger E1731063.BD12.137S?

The Breitling Avenger E1731063.BD12.137S features a 24mm lug width. This measurement is structural and compatible exclusively with 24mm straps. Always verify the measurement between the case lugs before purchase.

Which strap material is best suited for the Breitling Avenger E1731063.BD12.137S?

For this 48mm titanium model, we recommend Nile crocodile or vegetable-tanned calf leather. Crocodile offers elegance and resilience, while calf develops authentic patina over time. For marine environments, double-layer nylon NATO provides the most reliable practical solution.

How do I change the strap on my Breitling Avenger?

Straps are replaced via the case lugs. Gently press the lug spring inward and remove the original strap. Insert the new strap, ensuring it is centred, and lock the lugs in position. For professional instruments like the Avenger, we recommend expert supervision to verify alignment.

Is an aftermarket strap compatible with reference E1731063.BD12.137S?

Yes, provided it is manufactured for the 24mm lug width. Quality aftermarket straps maintain identical attachment specifications to original equipment. Avoid low-cost straps with poorly finished steel lugs, as these cause lateral movement and accelerated wear.

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

A quality crocodile or calf strap, subjected to annual maintenance with specific balms and not exposed to prolonged humid climates, lasts approximately 5-7 years. Calf requires more attention during summer months. Casati Milano's warranty covers manufacturing defects for 18 months.
