Strap for Montbrillant 01 Red Gold / Mercury Silver / Air Racer

The Breitling Montbrillant RB013012.G710.223R has a lug width of 20mm. This measurement should be taken with a digital calliper placed between the inner walls of both lugs at the point where the strap meets the case. It is also advisable to check the lug length to determine whether a straight-end or tapered strap is the more appropriate choice.

For this red gold reference, a vegetable-tanned alligator strap in cognac or dark brown is the most aesthetically coherent choice. The belly grain of alligator leather complements the precious case finish without overpowering it. Shell cordovan is an excellent alternative, developing a warm patina over time that harmonises naturally with the chromatic warmth of red gold.

The strap is replaced using a fine-tipped spring bar tool, applying gentle lever pressure against the spring bar inside the lug. Work on a soft surface to protect the red gold case from scratches. If this is your first strap change or the lugs are particularly tight, it is advisable to consult a watchmaker or visit the Casati Milano atelier.

Yes, any strap with a 20mm lug width is technically compatible. Milano Straps offers a curated selection of handcrafted 20mm straps in various materials and finishes, all fitted with standard 1.5mm spring bars compatible with Breitling lugs. Options include deployant buckle and pin buckle configurations.

Longevity depends on material and usage. A high-quality vegetable-tanned alligator strap typically lasts between two and five years with regular wear. Shell cordovan offers greater durability due to its denser fibre structure. Moisture, perspiration, and UV exposure are the primary causes of degradation; periodic application of a suitable leather conditioner will significantly extend the strap's service life.
