Strap for Avenger Chronograph 45 Stainless Steel / Black / Military / Pin / Swiss Air Force Limited Edition

The Breitling Avenger A133171A1B1X1 features a lug width of 22mm. This measurement can be verified using a digital calliper placed inside the lugs, close to the case. Respecting this dimension is essential to ensure correct fitment and to maintain the visual balance proportionate to the 45mm case diameter.

The most suitable straps for the Breitling Avenger A133171A1B1X1 are those in hornback alligator leather, vegetable-tanned calfskin, or vulcanised rubber for sporting use. The 22mm lug width and 45mm case diameter require a strap with sufficient thickness and structure to support the case mass without deforming. Black or dark tobacco brown colourways offer the greatest coherence with the model's aeronautical aesthetic.

The strap on the Breitling Avenger A133171A1B1X1 is secured by standard 22mm spring bars. To replace it, use a spring bar tool or a flat-blade screwdriver with a protected tip to avoid scratching the case. Compress the spring bar inward, remove the strap, and insert the new one by aligning the spring bars with the lug holes. The operation takes under two minutes and requires no professional equipment.

Yes, the aftermarket offers extensive options compatible with the Breitling Avenger A133171A1B1X1, provided the lug width is precisely 22mm.

The lifespan of a leather strap on the Breitling Avenger A133171A1B1X1 depends on the material and maintenance routine.

A high-grade alligator strap can exceed 5 years. Milano Straps provides an 18-month warranty against manufacturing defects on all handcrafted straps.
