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-X3 TOURBILLON MICRO-ROTOR

The Bell & Ross BR-X3 TOURBILLON MICRO-ROTOR is noted for its comfortable 40mm square case with well-rounded edges and a bold, artistic design. Reviewers highlight its wearable case that seamlessly integrates with the strap and a well-executed dial structure. The watch features a Kenissi-manufactured calibre with a 70-hour power reserve and COSC certification, though one source notes the absence of hour markers on the dial. The BR-X3 TOURBILLON MICRO-ROTOR is priced at $7,200 USD. Overall, reviewers praise the Bell & Ross BR-X3 TOURBILLON MICRO-ROTOR for its comfortable wearability and artistic dial execution.

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.
