Frequently asked questions

What is the lug width of the Breitling Avenger AB0146101B1A1?

The Breitling Avenger AB0146101B1A1 features a lug width of 22mm. This measurement is taken with a digital calliper or a millimetre ruler placed between the inner walls of the lugs, where the strap is inserted. It is a standard measurement in the professional instruments segment, ensuring a wide availability of compatible aftermarket straps.

What is the best strap for the Breitling Avenger AB0146101B1A1?

For the Breitling Avenger AB0146101B1A1, the most coherent materials with the instrument's character are: smooth alligator in anthracite or navy blue for formal-sport contexts, vegetable-tanned calf leather in matte finish for a contemporary military aesthetic, vulcanised rubber for operational use, and ballistic nylon NATO for maximum versatility. The choice depends on intended use and colour palette preferences.

How do you change the strap on the Breitling Avenger AB0146101B1A1?

The strap on the Avenger AB0146101B1A1 is removed using a springbar tool, inserting the tip between the lug and the spring bar to compress it and release the strap. Care should be taken not to scratch the steel lugs — it is advisable to protect the case with a soft cloth. The original 22mm spring bars can be reused with the new strap.

Are there aftermarket straps compatible with the Breitling Avenger AB0146101B1A1?

Yes, the aftermarket for 22mm straps is extensive. The Breitling Avenger AB0146101B1A1 is compatible with any standard strap measuring 22mm at the attachment end and tapering to 20mm at the buckle.

How long does a leather strap last on a Breitling Avenger AB0146101B1A1?

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and exposure to moisture and perspiration. A high-grade alligator or vegetable-tanned calf strap, properly maintained, will last between 2 and 5 years with daily use. Avoiding prolonged water exposure and periodically applying a leather conditioner will significantly extend the strap's life. The Casati Milano guarantee covers 18 months against manufacturing defects.
