Strap for Montbrillant 01 Red Gold / Mercury Silver / Calf

The lug width of the Breitling Montbrillant RB013012.G736.431X is 20mm, measured internally between the two lugs of the case. This is a standard dimension that allows a broad selection of quality aftermarket straps, provided the end-piece curvature is verified for compatibility with this specific case profile.

For the Montbrillant RB013012.G736.431X in 18-carat red gold, a vegetable-tanned alligator strap in bordeaux, cognac or mid-brown tobacco tones offers the most coherent pairing: the natural grain and developing patina of the leather complement the warm hues of the metal. Shell cordovan is a refined alternative for those seeking a slimmer profile and uniform grain. A deployant clasp in red gold completes the ensemble.

To replace the strap on the Breitling Montbrillant RB013012.G736.431X, a fine-tipped spring bar tool is required. Insert the tip into the spring bar slot between the lug and the strap, compress the spring bar and slide the strap free. Repeat on the other side. To avoid scratching the red gold case, use a plastic case protector or entrust the operation to a watchmaker or specialist atelier such as Casati Milano.

Yes. The Breitling Montbrillant RB013012.G736.431X features a standard 20mm lug width, accepting aftermarket straps from any manufacturer conforming to that measurement. Milanostraps.it offers a curated selection of handcrafted 20mm straps in alligator, calf, shell cordovan and other materials, vegetable-tanned and hand-finished, fully compatible with this reference.

The lifespan of a leather strap depends on the material, frequency of wear and exposure conditions. A high-quality vegetable-tanned alligator strap, worn with care and kept away from excessive moisture and perspiration, retains its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, owing to its denser fibre structure, can exceed 5 years. Milanostraps.it provides an 18-month guarantee against manufacturing defects on all straps.
