Frequently asked questions
What is the lug width of the Breitling Montbrillant RB013012.G736.724P?
The Breitling Montbrillant RB013012.G736.724P has a lug width of 20mm. This is the measurement to specify when purchasing any compatible aftermarket strap. To verify it, measure the internal distance between the two lugs using a digital calliper.
What is the best strap for the Breitling Montbrillant RB013012.G736.724P in red gold?
For the 18k red gold version with blue dial, the most coherent pairing is a cognac or tobacco brown alligator strap with vegetable tanning, which complements the warm tonality of the case. Alternatively, a bordeaux shell cordovan offers a compact grain and a character patina. For a more sporting look, a blue and grey nylon NATO echoes the dial's colour palette.
How do you change the strap on a Breitling Montbrillant?
The strap on a Breitling Montbrillant is removed using a spring bar tool or fine-tipped lever, sliding out the spring bar that secures the strap to the case lugs. Care should be taken to avoid scratching the red gold case: use a protective cloth and, if unfamiliar with the process, entrust the operation to a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Breitling Montbrillant RB013012.G736.724P?
Yes. Any strap with a 20mm attachment width is technically compatible with the Montbrillant RB013012.G736.724P, provided it uses standard spring bars. Milano Straps offers a curated selection of 20mm straps in alligator, calf leather, shell cordovan, NATO and rubber, handcrafted and available in bespoke versions through Casati Milano.
How long does a leather strap last on a Breitling Montbrillant?
The lifespan of a leather strap depends on leather quality, frequency of use and exposure to perspiration and moisture. A high-quality alligator or shell cordovan strap, maintained regularly with appropriate products, can last between three and six years with daily wear. Vegetable-tanned straps develop a personal patina over time and gradually soften whilst retaining structural integrity for years.
