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 C60 Trident GMT 300

Owners widely praise the Christopher Ward C60 Trident GMT 300's build quality and finishing, finding it a serious alternative to established Swiss brands. The 40mm size is considered comfortable with good wrist presence, and the lume is fantastic. The Sellita SW330-2 movement is noted as slim for a GMT, with one owner reporting accuracy of +5 seconds per week. Some owners dislike the older Bader bracelet and wish for better AR coating, while a reviewer noted the handset could be updated. On balance, owners and reviewers rate the Christopher Ward C60 Trident GMT 300 highly for its exceptional build quality and finishing at its price point.

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.
