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.

Citizen Promaster Skyhawk U830

The Citizen Promaster Skyhawk U830 is praised for its updated 43mm titanium case, legible memory-in-pixel display, and cleaner, less cluttered design compared to previous versions. Reviewers highlight its versatile contemporary look and enhanced functionality from the caliber U830, while owners appreciate the MIP display and screw-down caseback. Some users find the interface clunky and the face busy, particularly noting the "calendar" label and the lack of radio or GPS time synchronization, with one owner finding the 45mm size and busy subdials less useful for non-pilots. On balance, owners and reviewers rate the Citizen Promaster Skyhawk U830 highly for its impressive technology and improved legibility in a contemporary package.
