The watch features a Kenissi-manufactured calibre with a 70-hour power reserve and COSC certification, though one source notes the absence of hour markers on the dial. The BR-X3 TOURBILLON MICRO-ROTOR is priced at $7,200 USD. Overall, reviewers praise the Bell & Ross BR-X3 TOURBILLON MICRO-ROTOR for its comfortable wearability and artistic dial execution.

The Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH is noted for its modern, Transformer-like 45mm case and superb, qualitative finishing on its skeletonized sapphire dial. The manually wound BR-CAL.283 movement offers a 4-day power reserve. However, the movement's use of a Dubois-Depraz module over an ETA base is a point of consideration against competitors with in-house calibers, and the watch carries a high price point, with limited editions ranging from $163,000 to $238,000. Overall, reviewers highlight the Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH's impressive finishing and unique aesthetic as key strengths, despite its considerable cost and modular movement construction.
