What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Zelos Spearfish GMT

The Zelos Spearfish GMT is widely praised for its exceptional value, with reviewers highlighting its superb finishing, flawless machining, and a tool-less micro-adjustment clasp that exceeds its price point. It features a La Joux-Perret G100 movement with a 68-hour power reserve, achieving an average accuracy of +2.6 seconds per day, or a Miyota 9075 movement offering flier-style GMT functionality. The 40mm case and bidirectional 48-click ceramic bezel are well-executed, though one reviewer noted a minor compromise in the end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and value proposition.
