Strap for BR-X1 Tourbillon Chronograph Instrument de Marine

The lug width of the BRX1-CHTB-CM is 24mm. This dimension refers to the internal space between the two lugs of the case. Measure directly between the front lugs to verify compatibility: the manufacturing tolerance is ±0.5mm.

African alligator in cognac or black tones is ideal for this model: the regular grain emphasises the geometric severity of the rose gold case. Quality alternatives include vegetable-tanned calf leather (which ages gracefully) and technical NATO in Cordura for a functional interpretation coherent with Bell & Ross's aeronautical heritage.

Use a spring bar tool to gently remove the internal spring from the lugs. Insert the flat tip into the spring slot, lifting slightly to release the old strap. Repeat on the other side. To install the new 24mm strap, align the ends with the lug holes and press the spring until you hear a click. Verify that the strap is symmetrical before fastening the buckle.

Yes, any strap with a 24mm lug width is compatible with the BRX1-CHTB-CM, provided that the ends (pommes) fit correctly into the case lugs. Artisanal quality straps, such as those crafted by Casati Milano, offer premium materials and refined stitching, with steel or titanium deployante and superior durability guarantees compared to standard straps.

A quality leather strap (African alligator or premium vegetable-tanned calf) lasts on average 3–5 years with moderate daily wear. Durability depends on humidity exposure, perspiration, UV rays, and frequency of wear. A premium African alligator strap lasts longer than standard calf leather. Casati Milano atelier offers 18-month warranty and maintenance services to extend strap life.
