The AVI RB011713, seen from the bench

The Breitling AVI RB011713 is a 43mm Red Gold chronograph that reinterprets 1950s aviation watches for modern wearers. It houses the in-house Breitling B01 manufacture movement, a COSC-certified chronometer with column wheel, small seconds at 9 o'clock, date window, and 70-hour power reserve visible through the sapphire caseback. The case diameter is 43mm with a lug width of 23mm, a specific dimension of the AVI family in this 43mm configuration that distinguishes it from standard 22mm sport watches.

Frequently asked questions

What is the lug width of the Breitling AVI RB011713?

The Breitling AVI RB011713 has a lug width of 23mm. This is a specific dimension of this 43mm configuration and should be verified with a digital calliper before ordering any aftermarket strap.

What is the best strap for the Breitling AVI RB011713 in Red Gold?

For a Red Gold case, the most suitable materials are alligator in tobacco or cognac tones, vegetable-tanned calf leather, and shell cordovan. These leathers complement the warm palette of the red gold and align aesthetically with the AVI's aviation heritage.

How do you change the strap on the Breitling AVI RB011713?

The strap is removed using a double-ended spring bar tool, inserted into the hole on the lug to compress the spring bar. Care must be taken to avoid scratching the Red Gold case. It is advisable to work on a soft surface and, if inexperienced, to rely on a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling AVI RB011713?

Yes. The standard 23mm lug width allows the fitting of high-quality handcrafted aftermarket straps. Milano Straps offers a curated selection of 23mm compatible straps in fine leathers with bespoke finishing, requiring no adapters.

How long does a leather strap last on a Breitling AVI RB011713?

Longevity depends on the material and usage. An alligator or shell cordovan strap, properly maintained and kept away from excess moisture and perspiration, can last between 3 and 5 years while retaining its shape and appearance. Vegetable-tanned calf develops character over time but is more sensitive to humidity. Casati Milano straps carry an 18-month warranty against manufacturing defects.
