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 Bronze

The Boldr Odyssey Bronze is widely praised for its robust, ship-like aesthetic and substantial feel, with its meteorite dial and OEM Horween strap highlighted as unique features. Owners feel the style, fit, finish, and specifications compensate for criticisms regarding the movements used at its price point. On balance, owners rate the Boldr Odyssey Bronze highly for its distinctive aesthetic and quality finishing.

From video reviewers

The 500m water resistance and Lumicast lume are standout features. The 45mm+ case size is a drawback for some wrists.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
