Strap for Montbrillant 01 Red Gold / Aurora Blue / Air Racer

The lug width of the Breitling Montbrillant RB013012.C896.223R is 20mm. This measurement refers to the internal distance between the two case lugs and determines the correct width for any replacement strap. To verify this on your own piece, the use of a digital calliper is recommended.

For the Montbrillant in red gold, the most appropriate materials are alligator leather in warm tones (tobacco brown, cognac, bordeaux) and shell cordovan, both of which develop a patina in keeping with the character of the reference. Vegetable-tanned leather offers superior durability and aesthetic ageing. A deployant clasp in red gold completes the metal pairing with full coherence.

The strap is removed using a thin-blade spring bar tool or a precision flat-head screwdriver, inserted into the spring bar slot between the lug and the strap, compressing the spring-loaded tips. No specialist tools are required, but care should be taken to avoid scratching the red gold case. It is advisable to rest the watch on a soft cloth during the operation.

Yes, any strap with a 20mm lug width and standard spring bars is compatible. Milanostraps.it offers a selection of artisan straps in 20mm suitable for this reference, crafted in alligator, calfskin, shell cordovan and rubber. It is important to ensure that the tail width (at the buckle end) is narrower than 20mm — typically 16 or 18mm — for correct passage through the fixed keeper.

Longevity depends on the material and daily use. A quality alligator strap with vegetable tanning, used in rotation with other straps and kept away from prolonged exposure to perspiration and water, typically lasts 3–5 years before showing significant signs of wear. Shell cordovan is the most durable option and can exceed 5 years while retaining a refined patina. Smooth calfskin straps have an average lifespan of 2–3 years with regular use.
