Frequently asked questions

What is the lug width of the Breitling Avenger A17331101B2A1?

The lug width of the Breitling Avenger A17331101B2A1 is 22mm. This measurement is taken directly on the case, using a calliper to measure the internal distance between the two lugs where the strap is fitted. All compatible straps must be exactly 22mm wide at the attachment point.

What is the best strap for the Breitling Avenger A17331101B2A1?

The most suitable materials for the Avenger A17331101B2A1 are vegetable-tanned calf leather in a vintage finish, matte alligator leather for a more formal look, ballistic nylon NATO for intensive daily use, and vulcanised rubber for sporting or marine environments. The choice depends on context and aesthetic preference, but all straps must fit a 22mm lug width.

How do you change the strap on the Breitling Avenger A17331101B2A1?

To replace the strap on the Avenger A17331101B2A1, you will need a spring bar tool. Insert the tip into the lateral slot of the spring bar, compress the spring pin and slide the strap free from the lug. Repeat on the other side. The new 22mm strap is pressed into the same slots. The procedure takes approximately two minutes and does not require professional watchmaking tools.

Are there aftermarket straps compatible with the Breitling Avenger A17331101B2A1?

How long does a leather strap last on the Breitling Avenger A17331101B2A1?

The lifespan of a leather strap depends on the quality of the hide, frequency of use and maintenance. A quality vegetable-tanned leather strap, rotated with other straps and kept away from excessive moisture, can last between two and five years. Milano Straps products carry an 18-month guarantee against manufacturing defects and are crafted from hides sourced from certified tanneries.
