Frequently asked questions

What is the lug width of the Breitling Avenger A1337111/BC28/101X/A20BA.1?

The lug width is exactly 24mm. This measurement must be respected with a tolerance of ±0.3mm to ensure perfect fit of the strap to the watch lug seats. Measurement is taken from the inside of the spring bar on one lug to the opposite lug seat, perpendicular to the case plane.

What is the best strap material for the Breitling Avenger?

This depends on intended use. Alligator in vegetable tanning offers maximum aesthetic refinement and develops natural patina over time. Shell cordovan provides brutal tactical solidity and aged burgundy coloration. Box calf ensures compactness and scratch resistance. NATO in ballistic nylon guarantees interchangeability and rapid drying in humid environments. Technical rubber eliminates all maintenance and reduces the Avenger to pure instrument.

How do I change the strap on the Breitling Avenger A1337111/BC28/101X/A20BA.1?

The Avenger uses standard 24mm straight pins. Position the watch case-side down on a soft support. Locate the small hole on the spring bar. Insert a pin remover tool or small needle into the seat and apply steady pressure to extract the pin. Repeat on the opposite lug. Position the new strap and reinsert the pins from the case side, synchronizing insertion on both pins simultaneously to avoid misalignment.

Which aftermarket strap is compatible with the Breitling Avenger A1337111/BC28/101X/A20BA.1?

Any artisanal quality strap certified to 24mm is compatible. Milano Straps catalogues a complete collection of 24mm straps in vegetable-tanned alligator, box calf, shell cordovan, ballistic NATO, and technical rubber, all dimensioned precisely for this model's lugs and shipped ready for installation. Every strap can be personalised in sizing, initials, and stitching thread.

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

This depends on material, frequency of use, and environmental exposure. High-quality vegetable-tanned alligator lasts 8–12 years in daily wear, developing striking patina. Shell cordovan resists 10–15 years due to fibre density. Box calf wears more quickly (5–8 years) but offers lower replacement costs. All Milano Straps straps include 18-month warranty and can be regenerated, repaired, or replaced by the Casati Milano atelier.
