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.

CWC SBS Black Ice Quartz Watch

Owners widely praise the CWC SBS Black Ice Quartz Watch for its legible, uncluttered dial, excellent Super-LumiNova lume, and robust build quality, noting its comfortable 12mm thickness and durable PVD coating. The bezel action is described as having zero back play, and the fixed lugs are appreciated for easy strap changes. One owner reported the lume is readable throughout the night, while another flagged a faulty mechanism requiring replacement and poor retailer customer service. The £700 price is considered high by some compared to similar quartz divers, leading to questions about its value. Overall, owners rate the CWC SBS Black Ice Quartz Watch highly for its bombproof, toolish design and practical aesthetics.
