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 A-T

The Citizen Promaster Skyhawk A-T is praised for its comprehensive feature set, including radio-controlled atomic timekeeping, a perpetual calendar, and a second time zone subdial. Reviewers note the titanium models offer good wearability, though one owner found the watch felt like a boat anchor. The stainless steel versions feature polished chamfers, brushed finishing, and a bidirectional bezel with a slide rule. Some models, particularly those with black hands against a black dial, have been criticized for poor readability, while others offer semi-skeletonized white sword hands and stencil numerals for improved legibility. On balance, owners and reviewers appreciate the Citizen Promaster Skyhawk A-T's extensive functionality and build, though legibility can be a concern on certain dial configurations.
