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 Sikorsky

The Citizen Promaster Sikorsky is a large 46mm watch honoring the S-92 helicopter, featuring a busy dial with red, white, blue, and yellow accents, and helicopter blade-shaped hands. It houses a solar-powered U680 movement with atomic time syncing. On balance, owners find the Citizen Promaster Sikorsky to be a unique, albeit cluttered, limited edition timepiece.
