Frequently asked questions

What is the lug width of the Breitling AVI AB0119131B1A1?

The lug width of the Breitling AVI AB0119131B1A1 is 23 mm. This measurement should be taken with a digital calliper positioned between the two lugs at the base of the case, on the six o'clock side. It is a non-standard width that requires straps specifically cut to 23 mm for a correct and precise fit.

What is the best strap for the Breitling AVI AB0119131B1A1?

For the Breitling AVI AB0119131B1A1, the most suitable materials are polished alligator leather for a formal register, vegetable-tanned calfskin for daily wear that develops an authentic patina over time, shell cordovan for those seeking durability and natural lustre, or moulded rubber for sporting use. A stainless steel deployant clasp is recommended for visual coherence with the brushed steel case and added security on the wrist.

How do you change the strap on the Breitling AVI AB0119131B1A1?

To replace the strap on the Breitling AVI AB0119131B1A1, a fine-tipped spring bar tool is required. Insert the tool into the gap between the lug and the strap, compress the spring bar and slide it out. Take care not to scratch the steel case: place a soft cloth beneath the case and work on a stable surface. The original spring bars have a diameter of 1.5 mm.

Are there aftermarket straps compatible with the Breitling AVI AB0119131B1A1?

Yes. Any strap with a 23 mm lug width is technically compatible with the Breitling AVI AB0119131B1A1. Milano Straps offers a curated selection of handcrafted 23 mm straps in various materials and finishes, manufactured to precise millimetre tolerances to ensure an optimal fit without any modification to the original lugs.

How long does a leather strap last on a Breitling AVI AB0119131B1A1?

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned calfskin strap lasts on average 2 to 4 years with daily wear. Shell cordovan can exceed 5 years owing to the density of its fibres. Alligator leather, if properly maintained with dedicated creams and kept away from prolonged water exposure, typically lasts 3 to 5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
