Frequently asked questions

What is the lug width of the Breitling Montbrillant R2133012G624220R?

The Breitling Montbrillant R2133012G624220R has a lug width of 22mm. This measurement should be taken directly between the two lugs at the point where the strap attaches to the case, using a calliper or a millimetre ruler. It is essential to measure at that precise point rather than at the mid-section of the strap to ensure a correct fit.

What is the best strap for the Breitling Montbrillant R2133012G624220R?

For the Montbrillant in 18k red gold, an alligator strap with symmetrical grain in mahogany, bordeaux or dark tobacco tones is the most coherent choice given the watch's aesthetic. Alternatively, a vegetable-tanned leather strap develops a natural patina that complements the instrument-oriented character of the chronograph. A red gold or champagne PVD deployant clasp eliminates visual interruptions on the wrist.

How do you change the strap on a Breitling Montbrillant R2133012G624220R?

Strap replacement requires a spring bar tool to remove the spring bars from the 22mm lugs. Insert the flat or forked tip into the gap between the strap and the lug, compress the spring bar and release the strap. Care should be taken to avoid scratching the red gold case: it is advisable to protect the surfaces with adhesive tape or to entrust the operation to a watchmaker.

Are there aftermarket straps compatible with the Breitling Montbrillant R2133012G624220R?

Yes. Any strap with a 22mm lug width is technically compatible with the Montbrillant R2133012G624220R, provided the curvature of the ends suits the lug profile. Milano Straps offers a selection of handcrafted 22mm straps in leather, alligator and alternative materials, made to fit the geometry of this case.

How long does a leather strap last on a Breitling Montbrillant?

A quality leather strap on a Montbrillant typically lasts between 18 and 36 months with daily wear, depending on the type of leather, maintenance and exposure to perspiration and moisture. Vegetable-tanned leather develops a patina but requires periodic treatment with natural conditioning creams. Alligator is more resistant to surface moisture but should be kept away from water and direct contact with fragrances.
