Strap for Aviator 8 B01 Chronograph 43 Red Gold / Bronze / Alligator / Folding

The lug width of the Breitling AVI RB0119131Q1P2 is 23mm. This is a non-standard size that requires straps cut specifically to this measurement. To verify it independently, measure the gap between the lugs on the case back using a digital calliper.

For an 18k Red Gold case, the most suitable strap is a vegetable-tanned alligator in bordeaux or midnight blue, paired with a three-piece folding deployant clasp in red gold. The natural belly grain of alligator leather harmonises with the brushed surfaces of the case without visual competition. Alternatively, a tobacco brown box-calf leather strap offers versatility and develops a distinctive patina over time.

The strap is replaced by compressing the spring bars housed in the 23mm lugs. A spring bar tool is required — insert the forked tip into the gap between the strap end and the lug to compress the bar and release it. When working with a red gold case, it is advisable to protect the case surfaces with soft masking tape or to entrust the operation to a watchmaker or the Casati Milano atelier.

Yes, high-quality aftermarket straps compatible with the 23mm lug width of the Breitling AVI RB0119131Q1P2 are available. It is essential to select artisan manufacturers who work specifically on this measurement, ensuring a precise cut and correct stitching geometry at the lug end. Milano Straps offers a curated selection of 23mm straps made to measure, available online or customisable through the Casati Milano atelier.

A high-quality leather strap — vegetable-tanned alligator or box-calf — worn daily typically lasts between 2 and 4 years, with significant variation depending on care and conditions of use. Contact with water, perspiration and perfume accelerates fibre degradation. Regular conditioning with a leather-specific cream and rotating between multiple straps can considerably extend the lifespan of the piece. Milano Straps provides an 18-month warranty against manufacturing defects.
