Frequently asked questions

What is the lug width of the Breitling Montbrillant A1935012.C667?

The lug width of the Breitling Montbrillant A1935012.C667 is 20 mm. This measurement should be taken internally between the two parallel lugs of the case using a digital calliper, to ensure correct compatibility with any replacement strap.

What is the best strap for the Breitling Montbrillant A1935012.C667?

For the Montbrillant A1935012.C667, a square-scaled alligator strap with vegetable tanning is the most coherent choice for formal use, as its three-dimensional texture complements the complexity of the dial. For sporting or everyday wear, a smooth brown tabac calfskin or a robust nylon NATO strap suits the watch's aviator heritage perfectly.

How do I change the strap on the Breitling Montbrillant A1935012.C667?

The strap on the Montbrillant A1935012.C667 is secured by standard spring bars fitted into the lugs. Using a spring bar tool, compress the spring bars laterally to release them, remove the existing strap, and fit the new one by ensuring both spring bars are correctly seated in their respective lug holes. The operation takes only a few minutes and can be carried out at home with care.

Are there aftermarket straps compatible with the Breitling Montbrillant A1935012.C667?

Yes, any strap with a 20 mm lug width is technically compatible with the Breitling Montbrillant A1935012.C667. Milano Straps offers a curated selection of handcrafted straps in various leathers and materials, made specifically for this width, with stainless steel buckles and deployant clasps that complement the original case finish.

How long does a leather strap last on a Breitling Montbrillant A1935012.C667?

The lifespan of a leather strap depends on the material and daily care. A high-quality vegetable-tanned alligator strap, kept away from excessive moisture and treated periodically with appropriate leather cream, will typically last 3 to 5 years with daily wear. Shell cordovan, owing to its exceptional fibre density, can exceed 5 to 7 years whilst developing a distinguished patina over time. Milano Straps provides an 18-month guarantee against manufacturing defects on all handcrafted straps.
