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 True GMT

The Christopher Ward C63 True GMT is widely praised for its in-house CW-002 caliber, which offers a 120-hour power reserve and COSC certification. Owners find the 39mm case size comfortable, though some note it wears closer to 40-41mm. While the PVD hands provide good contrast and the lume is praised for readability, one owner felt the orange accent lacked pop and the gloss dial/text combo appeared cheap in certain lighting. One owner also noted a perceived slight difference in production quality compared to a sibling model's bracelet. Overall, owners and reviewers rate the Christopher Ward C63 True GMT highly for its impressive power reserve and COSC-certified movement at its price point.

From video reviewers

The case finishing is praised for its polished and curved surfaces. The watch uses a Sellita SW330-2 movement. Reviewers disagree on the case size, with one noting 40.5mm and another highlighting a 36mm option.

Yema Superman Steel CMM.10

Owners widely praise the Yema Superman Steel CMM.10 for its refined casework, including polished lug bevels and an elegant crown guard, and its comfortable 39mm x 10.5mm dimensions. The glossy black lacquer dial and bezel insert are noted for adding depth, and the in-house CMM.10 movement is reported to be accurate, with one owner observing a loss of only 2 seconds over 2 days. The scales bracelet is described as gorgeous and nearly invisible on the wrist, though some find its polished center links too flashy. One reviewer flagged the signature bezel lock mechanism as flimsy and inconvenient. The CMM.10 automatic movement offers a 70-hour power reserve and is regulated to within +5/-3 seconds per day. On balance, owners and reviewers rate the Yema Superman Steel CMM.10 highly for its refined finishing and comfortable wearability at its price point.

From video reviewers

The Yema Steel features an in-house movement with a micro-rotor, one of the most beautiful at this price point. The watch's clasp feels a bit thin, which is a notable drawback. Reviewers disagree on the movement's power reserve, with one reviewer noting a 42-hour reserve and the other not mentioning power reserve at all.
