Frequently asked questions

What is the lug width of the Breitling Avenger A1337111/G779/439X/A20BA.1?

The lug width is 24 millimetres. This dimension is standard for the 48mm Avenger model and allows pairing with straps proportionate to the case mass. To verify compatibility, measure the distance between the inner shoulders of the upper lugs on the case.

What is the best strap for this Breitling Avenger?

For the Breitling Avenger A1337111/G779/439X/A20BA.1, leather in supreme vegetable tanning (dark brown, black, burgundy) with grainy texture that contrasts the case's satin finish is ideal. Excellent alternatives include vulcanised rubber straps for professional or marine environments, or cotton-nylon NATO straps for military appeal.

How do you change the strap on this watch?

The strap is changed by removing the spring bars connecting the strap to the case lugs. Use a dedicated tool to gently press the two pins of the bars from inside, extracting the old strap and inserting the new one with the lugs seated on the case lugs. Ensure the bars click correctly into position.

How long does a leather strap last on this watch?

A quality leather strap, with artisanal vegetable tanning, has an average lifespan of 3-5 years with moderate daily use. Durability depends on humidity, sun exposure and cleaning frequency. Straps crafted by Casati Milano include an 18-month guarantee and can be renewed upon request.
