Strap for Avenger B01 Chronograph 44 Stainless Steel / Blue / Bracelet

The lug width of the Breitling Avenger AB0147101C1A1 is 22mm. This measurement is taken with a digital calliper positioned between the two lugs at the narrowest point where the strap attaches. It is a standard dimension within the 44mm sport-professional segment and allows for a wide selection of quality aftermarket straps.

The choice depends on the intended use. For professional and formal occasions, a 22mm alligator belly or vegetable-tanned calf leather strap complements the in-house Caliber B01 without undermining the case's technical character. For sport use or humid environments, a ballistic nylon NATO or vulcanised rubber strap offers durability and comfort. A deployant clasp is recommended on any material to preserve the strap's shape over time.

The strap on the Avenger AB0147101C1A1 is replaced using a fine-tipped spring bar tool or a dedicated watch knife, inserted into the spring bar slot visible on the lug. With gentle lateral pressure the spring bar releases and the strap slides free from the lug. Care should be taken to avoid scratching the stainless steel case: placing a soft cloth beneath the watch during the operation is advisable.

Yes. Any strap with a standard 22mm attachment and spring bars is compatible with the Avenger AB0147101C1A1. Milano Straps handcrafted straps are made specifically for this lug width, with options in Tuscan vegetable-tanned calf, CITES-certified alligator, NATO nylon and technical rubber. The construction quality of aftermarket straps can equal or exceed that of the original Breitling strap in terms of materials and finishing.

The longevity of a leather strap depends on the quality of the tanning, hide thickness and frequency of wear. A high-quality vegetable-tanned calf strap, 3–4mm thick with waxed thread stitching, can last between 3 and 6 years with ordinary care — kept away from prolonged water exposure and conditioned periodically. Alligator tends to outlast calf leather owing to the density of its grain structure. The patina that develops over time is regarded as an added value by collectors.
