The Bell & Ross BR-X1 TOURBILLON ROSE GOLD DIAMONDS is a luxurious, technically advanced timepiece with a modern, drone-inspired design and a skeletonized movement. Owners and reviewers highlight its unique, Transformer-like evolution of the BR 01, featuring switch-style or rocker-style chronograph pushers and a diamond-set bezel that some describe as fitting for a Bond villain. The watch houses a manually wound caliber BR-CAL.283 movement with a 4-day power reserve, operating at 3Hz, and includes time, subsidiary seconds via the tourbillon, a 30-minute monopusher chronograph, and a power reserve indicator.
