What people say

Owners + reviewers, side by side

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

Bremont Altitude Perpetual Calendar GMT

The Bremont Altitude Perpetual Calendar GMT is a highly exclusive piece, with one owner noting its $44,000 price point raises questions about its target audience and suggesting it may be a limited production showpiece. Reviewers highlight its refined Trip-Tick case, now featuring softer curves, a 42mm diameter, and a 12.23mm thickness in grade 2 titanium, though the oversized crowns are flagged as a potential drawback. Overall, owners and reviewers acknowledge the Bremont Altitude Perpetual Calendar GMT as a distinctive, albeit niche, high-complication offering with a notable case refinement.

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.
