Frequently asked questions

What is the lug width of the Breitling AVI R233801A1B1R1?

The Breitling AVI R233801A1B1R1 has a lug width of 22mm. This is the measurement to use when selecting any compatible aftermarket strap, and can be verified with a digital calliper inserted between the lugs flush against the case.

What is the best strap for the Breitling AVI R233801A1B1R1 in Red Gold?

For the Red Gold case, the most suitable straps are in tabacco brown or cognac alligator, Tuscan vegetable-tanned calf leather in warm tones, or shell cordovan. These materials complement the chromatic warmth of the rose gold and enhance the aeronautical profile of the chronograph.

How do you change the strap on the Breitling AVI R233801A1B1R1?

The strap is removed using a spring bar tool inserted into the lug notch to compress the spring bars and release the strap. A flat-tip tool is recommended to avoid scratching the Red Gold case. The operation does not require a watchmaker.

Are there aftermarket straps compatible with the Breitling AVI R233801A1B1R1?

Yes. Any strap with a 22mm attachment is compatible with the Breitling AVI R233801A1B1R1, provided it uses standard 22mm spring bars. Milano Straps offers a selection of handcrafted straps in 22mm, available online or customisable through the Casati Milano atelier.

How long does a leather strap last on a Breitling AVI?

The lifespan of a leather strap depends on the material and care: a quality alligator or shell cordovan strap, with regular use, typically lasts 2–4 years. Vegetable-tanned calf leather, being more porous, requires periodic treatment with neutral wax and lasts approximately 1–3 years. Avoiding prolonged contact with water and perspiration significantly extends the strap's life.
