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.

Seestern S446 GMT

Owners widely praise the Seestern S446 GMT for its stunning finishing and extreme value, with a sapphire crystal and adjustable clasp. The winding action is noted as buttery smooth, and the 39.5mm case size is considered very wearable. Some owners, however, flag the lume as a weak point and one owner found the bracelet clasp lacked sufficient micro-adjustment. The Seestern S446 GMT is considered an extreme value for the dollar. Overall, owners rate the Seestern S446 GMT highly for its exceptional finishing and value proposition at its price point.
