What people say

Owners + reviewers, side by side

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

Christopher Ward C63 Valour

Owners widely praise the Christopher Ward C63 Valour for its beautiful, deep dial with 3D applied markers and symmetric chronograph design, with some calling it one of the best-looking and most affordable chronographs available. Reviewers note the 39mm wide, 11.55mm thick Light-catcher case with flowing curves and contrasting finishes. The watch is powered by a thermocompensated, chronometer-certified quartz ETA G10.212 AD movement, with ETA claiming ±10 seconds per year accuracy via PreciDrive technology. However, some owners question the use of a quartz movement in a watch of this caliber, though others defend it for reliability and thinner profiles, while also debating if its claimed accuracy meets High Accuracy Quartz (HAQ) standards. Overall, owners and reviewers appreciate the Christopher Ward C63 Valour for its striking aesthetics and value, with the primary point of contention being its quartz movement.

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.
