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 Black Shadow

Owners widely praise the Christopher Ward Twelve X Black Shadow's impressive finishing for its price point and the quality of its bracelet. Some owners, however, feel the $4,865 price is high for the brand, while others argue it offers strong specifications for the money. Reviewers note the skeletonized COSC-certified SH21 movement provides a 120-hour power reserve, but legibility suffers due to the skeletonization and the watch's increased thickness is noticeable. One owner reported sharp edges on bracelet links and unfinished clasp surfaces, leading to a return, despite finding the case and dial appealing. On balance, owners and reviewers rate the Christopher Ward Twelve X Black Shadow highly for its finishing and value, with the skeletonized movement being a key draw.
