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.

Boldr Odyssey Regatta

The Boldr Odyssey Regatta is noted for its robust functionality and utilitarian design, powered by a Valjoux 7750 Elaboré movement. It features a tachymeter bezel graduated in knots and offers 500m water resistance. While its 45.5mm diameter, 18.2mm thickness, and 245g weight make it a substantial timepiece, it wears better than its dimensions might suggest. Overall, owners and reviewers highlight the Boldr Odyssey Regatta's workhorse movement and functional tool-watch capabilities.

From video reviewers

500m water resistance is a consistently praised feature. The watch's significant weight and large case size were noted as drawbacks by multiple reviewers. Reviewers disagreed on whether the bezel's 15-minute markings were redundant given the regatta complication.
