What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH

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.

Spinnaker Tesei Mille Metri GMT

The Spinnaker Fleuss Midnight Black features a reliable and accurate Japanese TMI NH35 Automatic Movement with 3 Hands and Date. A potential drawback is the watch's relatively low 15 ATM water-resistance rating compared to other watches in its class. Reviewers disagree on the watch's suitability for larger wrists, with one reviewer noting a 43mm diameter and 51mm lug-to-lug fit, while the other mentions a 51mm lug-to-lug measurement.
