What people say

Owners + reviewers, side by side

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

Bremont Supernova

The Bremont Supernova is praised for its new ENG375 movement, big date, and power reserve indicator, with its 40mm steel case featuring mixed finishing and an integrated bracelet. Owners note good but not great lume, well-balanced proportions, and a premium feel for its price, despite a 173-gram weight. Some community members find the design derivative and the £8,000 price tag overly optimistic, with mixed views on the date window and crown guard. The proprietary Trip-Tick case construction offers shock protection, and the movement provides a 65-hour power reserve. Overall, owners and reviewers highlight the integrated bracelet and proprietary movement as key strengths of the Bremont Supernova.

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.
