Strap for BR-X1 Carbone Forgé

The lug width of the BRX1-CE-CF-BLACK is 24mm. This measurement represents the internal distance between the two pins of the original strap and defines a remarkably rare specification in the modern watch landscape. A compatible strap must respect this dimension with zero tolerance to guarantee precise and secure mounting.

For the BRX1-CE-CF-BLACK, the most legitimate choice is a fine-grain alligator strap, preferably in black or dark anthracite, which harmonises seamlessly with the ceramic case without competing with the watch's formal geometry. An equally compelling alternative is vegetable-tanned calf leather, offering initial rigidity and progressive patina development over time. Avoid NATO straps and warm-toned cinturini: the BRX1's architecture is decidedly cool and geometric.

Changing the strap on this model requires removal of the undersized pins from both sides of the case. Use a dedicated spring bar tool, inserting it into the small notch of the spring and gently lifting the pin until extraction. Replace the old strap with the new one, ensuring the pins are mounted securely and that the new strap lug width is certified at exactly 24mm.

Yes, provided the aftermarket strap has a lug width of exactly 24mm and is constructed to equivalent quality standards. Bell & Ross does not employ proprietary strap systems, so any high-quality 24mm strap (alligator, vegetable-tanned calf, technical rubber) is compatible. Always verify the supplier's specifications before purchase.

Durability depends on leather quality and usage conditions. A well-made alligator or vegetable-tanned calf strap typically withstands 4–6 years of daily wear with minimal maintenance (air-drying after water exposure, avoiding prolonged direct heat). Premium leather on vegetable tanning can last 7–10 years. Critical factors include body perspiration, ambient humidity, and frequency of wear.
