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 Mellor-72 Mechanical Watch

The CWC Mellor-72 Mechanical Watch is widely praised for its authentic, utilitarian design and satisfying hand-wound Sellita SW210 movement, with owners noting a smooth winding action and excellent accuracy, including one report of zero seconds deviation over 24 hours. Reviewers highlight the era-appropriate dial and functional "piece of kit" appeal, though some find the 35mm case small by modern standards and legibility can be impacted by the domed hesalite crystal. Owners report issues with fixed lug bars being poorly filled in and fogging inside the crystal, while others state no water resistance problems. Overall, owners and reviewers appreciate the CWC Mellor-72 Mechanical Watch for its genuine military heritage and functional charm, despite some practical drawbacks.
