Strap for Avenger Chronograph GMT 45 Stainless Steel / Black / Strap - Pin

The Breitling Avenger A24315101B1X1 has a lug width of 22mm. This measurement refers to the internal distance between the two lugs and can be verified with a millimetre calliper. Any compatible strap must feature a 22mm attachment end.

For sporting or operational use, a high-resistance nylon NATO or vulcanised rubber strap is the most functionally appropriate choice. For formal or business settings, a vegetable-tanned alligator or calfskin strap in neutral tones — black, navy blue, slate grey — complements the 45mm case without undermining the watch's technical character.

The strap is removed using a fine-tipped spring bar tool: compress the spring bar housed between the lugs and slide the strap free. Care should be taken to avoid scratching the steel lugs. It is advisable to work on a soft surface and, if in doubt, to consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 22mm attachment and 20mm tail is technically compatible with the Breitling Avenger A24315101B1X1. Milano Straps offers a curated selection of handcrafted leather, NATO and rubber straps specifically suited to this lug width, with standard buckles and deployant clasps in brushed steel.

Longevity depends on the material and conditions of use. A vegetable-tanned calfskin strap, regularly conditioned and protected from excessive moisture, typically lasts between 2 and 4 years with daily wear. Premium alligator leather can exceed 5 years. Milano Straps provides an 18-month warranty against manufacturing defects on all leather straps.
