Strap for BR-X1 Tourbillon Chronograph Sapphire

The lug width of the Bell & Ross Instruments BRX1-CHTB-SAPHIR is 24mm. This measurement represents the distance between the two spring bars that connect the strap to the case. It is essential to verify this dimension before purchasing an aftermarket strap to ensure mechanical compatibility and correct application.

The choice of strap depends on intended use and aesthetic preference. For maximum refinement, alligator leather in vegetable tanning with a matte black finish complements the watch's technical identity with a patina that develops over time. Alternatively, high-quality European chrome-tanned calf offers superior tactile consistency, whilst shell cordovan in cognac tone introduces warmth that dialogues with the titanium case. For more technical usage, a rubber strap with titanium deployant reinforces the watch's instrumental DNA.

To change the strap, use a spring bar tool (piston extractor). Procedure: 1) Position the watch on a soft surface to protect the case; 2) Insert the pointed tip of the tool under the spring bar; 3) Apply pressure to release the bar from its seat; 4) Extract the spring bar; 5) Align the new strap's holes with the bar; 6) Reinsert the spring bar into the seat. We recommend performing this operation on a well-lit, protected surface.

Any strap with a 24mm lug width is compatible with the BRX1-CHTB-SAPHIR. Milano Straps offers a curated collection of 24mm-compatible straps in alligator, calf leather, shell cordovan, natural rubber and fluoroelastomer. All straps are customisable in length, width and constructive details, ensuring perfect application.

The durability of a leather strap depends on material type and usage conditions. Alligator or calf in vegetable tanning, with regular maintenance (gentle cleaning and occasional conditioning), can last 5–7 years of daily wear. Shell cordovan, being more robust, may exceed 7–8 years. Natural rubber has a shorter lifespan of 3–4 years, whilst fluoroelastomer maintains its properties for 5–6 years. Proper storage (away from heat and extreme humidity) significantly extends strap longevity.
