The AVI A17314101C1A1 (aka: A1731410.C998.187A), seen from the bench

The Breitling AVI A17314101C1A1 is a modern reinterpretation of the 1953 Ref. 765 AVI, chosen by Allied military aviation for its legibility and robustness. It features a 41mm stainless steel case with a black matte dial, luminescent indices, and integrated pump chronograph pushers. The Breitling Caliber 17 movement, based on the ETA 2892-A2, provides hours, minutes, seconds, and date with approximately 42 hours of power reserve. Water-resistant to 100m with a unidirectional bezel, it has a 21mm lug width designed for structurally robust straps.

Frequently asked questions

What is the lug width of the Breitling AVI A17314101C1A1?

The lug width of the Breitling AVI A17314101C1A1 is 21mm. This is a non-standard measurement in the watchmaking industry, requiring straps specifically produced for this size. To verify it accurately, use a digital calliper to measure the internal distance between the two lugs close to the case, with the original strap removed.

What is the best strap for the Breitling AVI A17314101C1A1?

The choice depends on the context of use. For formal or business wear, a black or dark grey alligator strap with contrast stitching is the most coherent option. For everyday casual use, a vegetable-tanned calfskin strap in tobacco brown develops a natural patina over time, complementing the AVI's vintage aesthetic. For sport or marine use, vulcanised rubber or a two-colour nylon NATO are the most practical options. All must have a 21mm lug width.

How do you change the strap on the Breitling AVI A17314101C1A1?

The strap is removed using a springbar tool, which compresses the spring bars housed within the case lugs. Once compressed, the strap slides out laterally. The operation is fully reversible and does not require professional tools, though care should be taken to avoid scratching the steel case. The replacement strap must have a 21mm lug width.

Are there aftermarket straps compatible with the Breitling AVI A17314101C1A1?

Yes. milanostraps.it offers a selection of handcrafted straps in 21mm lug width compatible with the Breitling AVI A17314101C1A1. Materials include calfskin, alligator, shell cordovan and rubber, with various buckle options including standard tang buckle and deployant clasp. Each strap is handmade and available either ready-to-ship or bespoke through the Casati Milano atelier.

How long does a leather strap last on a Breitling AVI A17314101C1A1?

The lifespan of a leather strap depends on the quality of the hide, frequency of use, and exposure to perspiration and moisture. A quality calfskin strap, properly maintained with appropriate leather care products, can last between 2 and 4 years with daily wear. An alligator or shell cordovan strap, being denser and more compact materials, may exceed 5 years while retaining structural integrity. Casati Milano straps carry an 18-month warranty against manufacturing defects.
