Strap for Montbrillant 01 Red Gold / Aurora Blue / Croco

The Breitling Montbrillant RB013012.C896.718P has a lug width of 20mm. This is the standard measurement for this reference, making it compatible with any 20mm strap — whether original Breitling or aftermarket.

For the red gold 18k case of the Montbrillant, the most suitable materials are vegetable-tanned alligator leather in warm tones (cognac, tobacco, bordeaux) and shell cordovan for those seeking a deep patina over time. Box-calf leather is a more understated but equally refined alternative.

The Montbrillant strap is secured by standard 20mm spring bars. A fine-tipped spring bar tool is sufficient to remove the original strap and fit the new one. It is advisable to work on a soft surface to protect the red gold case from accidental scratches.

Yes. Any strap with a 20mm attachment and standard length (approximately 120/75mm) is technically compatible. Milano Straps offers a selection of handcrafted 20mm straps specifically suited to this reference, including options in alligator, calfskin and rubber.

The lifespan of a leather strap depends on leather quality, care and daily use. A handcrafted alligator or shell cordovan strap that has been vegetable-tanned and kept away from water and perspiration, treated periodically with neutral wax, can last between 3 and 7 years while retaining a dignified patina. Calfskin straps generally have a shorter lifespan of 1 to 3 years with regular wear.
