Frequently asked questions

What is the lug width of the Breitling AVI A17314101B1A1?

The Breitling AVI A17314101B1A1 features a lug width of 21mm. This is a non-standard size compared to the more common 20mm and 22mm, so it is essential to select straps specifically made for this width to ensure a precise fit and avoid lateral play at the lugs.

What is the best strap for the Breitling AVI A17314101B1A1?

The most fitting options for the Breitling AVI A17314101B1A1, given its tool-watch character, are: vegetable-tanned calf leather for everyday wear with natural patina development, hornback or padded alligator for formal occasions, vulcanised rubber for sports use, and ballistic nylon NATO to honour its military heritage. A brushed steel deployant clasp pairs well with any leather strap.

How do you change the strap on a Breitling AVI A17314101B1A1?

To replace the strap on a Breitling AVI A17314101B1A1, use a spring bar tool to compress the spring bars laterally from inside the lugs. Remove the old strap, slide the new one into position, and ensure both spring bars click securely into the lug holes on each side. No case disassembly or watchmaker intervention is required.

Are there aftermarket straps compatible with the Breitling AVI A17314101B1A1?

Yes. Milanostraps.it offers a range of handcrafted aftermarket straps in 21mm width, fully compatible with the Breitling AVI A17314101B1A1. Straps are either made to measure or selected from references precisely calibrated to this lug width, with varying buckle-end and keeper widths to suit different buckle and deployant configurations.

How long does a leather strap last on a Breitling AVI A17314101B1A1?

The lifespan of a leather strap depends on the tanning process, daily use, and maintenance. A quality vegetable-tanned calf strap worn daily and kept away from excessive moisture and perspiration will typically last between two and four years. Alligator and shell cordovan straps, owing to their denser fibre structure, generally offer greater longevity. Casati Milano provides an 18-month guarantee against manufacturing defects.
