What people say

Owners + reviewers, side by side

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

Bremont Supermarine Chrono

The Bremont Supermarine Chrono's black dial and understated bezel markings allow it to transition effectively from rugged use to evening events. On balance, owners and reviewers find the Bremont Supermarine Chrono to be a handsome and functional watch, with its versatile dial design being a key strength.

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.
