The Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH is noted for its modern, Transformer-like 45mm case with switch-style chronograph pushers and a skeletonized movement visible through a sapphire dial. Reviewers praise its superb and qualitative finishing and dial. However, the watch is criticized for its high price, with limited editions ranging from $163,000 to $238,000, and its movement relies on a Dubois-Depraz module over an ETA base, a point of consideration against competitors with in-house calibers. On balance, reviewers consider the Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH a significant image-builder for the brand, with its main drawbacks being its high price and modular movement.
Owners widely praise the Rolex Yacht-Master II's ingenious mechanical complexity, specifically its programmable regatta countdown timer with a flyback function and retrograde minute hand. Reviewers note the redesigned model features a 72-hour power reserve and accuracy to -2/+2 seconds per day. The 44mm case size is considered large by many, and its bold, "in your face" styling and busy dial are polarizing, with some finding it ugly and others gorgeous. The regatta timer complication is seen by some as overly niche and impractical, while others appreciate its unique aesthetic and satisfying flyback functionality. On balance, owners and reviewers rate the Rolex Yacht-Master II highly for its unique and complex regatta timer complication, despite its polarizing design and size.
