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 Twelve X Black Shadow

Owners widely praise the Christopher Ward Twelve X Black Shadow's impressive finishing for its price point and the quality of its bracelet. Some owners, however, feel the $4,865 price is high for the brand, while others argue it offers strong specifications for the money. Reviewers note the skeletonized COSC-certified SH21 movement provides a 120-hour power reserve, but legibility suffers due to the skeletonization and the watch's increased thickness is noticeable. One owner reported sharp edges on bracelet links and unfinished clasp surfaces, leading to a return, despite finding the case and dial appealing. On balance, owners and reviewers rate the Christopher Ward Twelve X Black Shadow highly for its finishing and value, with the skeletonized movement being a key draw.

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.
