Strap for Montbillant Pink Gold / Silver

The lug width of the Breitling Montbrillant H4137012.G659 is 20mm. This is a standard measurement within Swiss chronography, ensuring a wide availability of compatible replacement straps. To confirm the measurement on your own piece, use a digital calliper to measure the internal distance between the two parallel lugs at the point closest to the case.

For the Montbrillant H4137012.G659 in 18k pink gold, a vegetable-tanned alligator strap with a centred cross grain is the most coherent choice: the natural texture of the leather complements the worked surfaces of the gold case. Alternatively, box-calf leather offers a more restrained register, while a fine-weave NATO reinterprets the Montbrillant's aviation heritage. A pink gold deployant clasp completes the pairing in the most appropriate manner.

The strap on the Montbrillant H4137012.G659 is replaced by acting on the spring bars that connect the strap to the case lugs. A dedicated spring bar tool, inserted into the side hole of the lug, is used to compress the bar and release the strap. The operation is straightforward but requires care to avoid scratching the pink gold case: it is advisable to protect surfaces with masking tape before proceeding.

Yes. Any strap with a 20mm lug width and straight ends is compatible with the Montbrillant H4137012.G659.

The lifespan of a leather strap depends on the material, frequency of use and maintenance. A quality vegetable-tanned alligator strap, with regular use and proper care (periodic conditioning with a dedicated cream, drying away from heat sources), has an average lifespan of 3 to 5 years. First-quality box-calf achieves similar results. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
