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 The Twelve 660

Christopher Ward The Twelve 660 owners widely appreciate its thin 6.6mm case, achieved partly by reducing bezel and caseback diameters, and its well-made construction and value proposition. However, the community is split on the manual wind and lack of a second hand, with some finding these features unnecessary while others enjoy the interaction and thinness they enable. The bracelet's butterfly clasp lacks micro-adjustments, and some find the 30m water resistance limiting. Overall, owners and reviewers rate Christopher Ward The Twelve 660 highly for its innovative thin case design and perceived value, despite differing opinions on its manual-wind-only, no-date configuration.
