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.

Christopher Ward Twelve X (Ti)

The Christopher Ward Twelve X (Ti) is praised for its exceptionally finished, lightweight titanium case and COSC-certified, skeletonized SH21 movement offering a 120-hour power reserve. Reviewers note its comfortable wearability due to the rounded case shape, despite a 12.3mm thickness, and highlight the micro-adjust clasp. Legibility is considered good for a skeletonized watch, though reduced compared to standard dials. One reviewer points out that the case chamfers may be prone to dings and the movement finishing does not reach higher-end standards. Overall, reviewers rate the Christopher Ward Twelve X (Ti) highly for its impressive case finishing and the value of its COSC-certified, in-house skeletonized movement.
