Strap for Montbrillant 01 Red Gold / Mercury Silver / Croco

The lug width of the Breitling Montbrillant RB013012.G736.728P is 20mm. This measurement corresponds to the internal distance between the two lugs of the case and is the key parameter for selecting a compatible replacement strap. It is advisable to verify this figure with a calliper before purchasing, particularly on well-worn examples.

For an 18-carat red gold case such as that of the Montbrillant RB013012.G736.728P, a semi-glossy alligator strap in bordeaux, cognac or dark brown is the most aesthetically coherent choice. Alternatively, vegetable-tanned calfskin or shell cordovan offer high durability and develop a distinctive patina over time. A deployant clasp in red gold or gold PVD completes the pairing, enhancing the visual symmetry with the case.

Strap replacement on the Breitling Montbrillant RB013012.G736.728P is carried out via the spring bars connecting the strap to the case lugs. A dedicated spring bar tool or a small flat-head screwdriver is sufficient to compress and release the spring bars. It is recommended to work on a soft surface to avoid scratching the red gold case. If in doubt, consult a watchmaker or the Casati Milano atelier.

Yes, any strap with a 20mm attachment width is technically compatible with the Breitling Montbrillant RB013012.G736.728P. The extensive range of handcrafted aftermarket straps — in alligator, calfskin, shell cordovan, NATO or rubber — available on milanostraps.it allows full personalisation of the watch whilst maintaining high quality standards, with no adapters or case modifications required.

Strap longevity depends on the material, frequency of use and exposure conditions. A vegetable-tanned calfskin strap, properly maintained, typically lasts 2–4 years with daily wear. Shell cordovan, owing to its dense fibrous structure, can last 5–7 years. Alligator leather, if kept away from moisture and treated periodically, retains structural and aesthetic integrity for 3–5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
