AVI A17315101C1X3— lug 21mm

The Breitling AVI A17315101C1X3 has a lug width of 21mm. This is a non-standard measurement, which means replacement straps must be specifically made for this width. Before purchasing an aftermarket strap, it is advisable to verify the measurement using a digital calliper placed internally between the two lugs at the spring bar position.

For the Breitling AVI A17315101C1X3, the most suitable materials are vegetable-tanned calfskin for an authentic vintage aesthetic, alligator with a regular grain for a more formal look, and ballistic nylon NATO for sporting contexts. The 41mm stainless steel case pairs well with straps in dark tones — black, tobacco brown, olive green — or in contrast with tan and cognac shades.

The strap on the Breitling AVI A17315101C1X3 is secured by standard spring bars. To replace it, use a bifurcated spring bar tool to release the bars from the lugs. The operation can be carried out carefully at home, or entrusted to a watchmaker or to the Casati Milano atelier for a professional replacement.

The lifespan of a leather strap for the Breitling AVI A17315101C1X3 depends on the quality of the hide and frequency of use. A quality vegetable-tanned calfskin strap typically lasts 2 to 4 years with daily wear, developing a characteristic patina over time. Alligator and shell cordovan, thanks to their denser fibre structure, generally offer greater longevity. Exposure to water, perspiration, and UV rays are the primary causes of wear.
