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.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
