Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Glycine Combat Sub for its exceptional value, smooth bezel action, and refined finishing for the price. The thin case, noted as 10.4mm or 10.8mm across different variants, and downward-curving lugs contribute to comfortable wearability, with many appreciating its unique, non-homage aesthetic. However, reviewers and owners consistently flag sub-par lume and an inconsistent power reserve. Some owners also express a preference for smaller case sizes within the line, with one noting the 42mm version's size led them to gift it away. On balance, owners and reviewers rate the Glycine Combat Sub highly for its excellent finishing and comfortable wearability at its price point.
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 size. The glossy black dial and bezel insert provide depth, and the in-house CMM.10 movement is noted for accuracy, with one owner reporting losing only 2 seconds in 2 days. The scales bracelet is described as gorgeous and comfortable, though some find its polished center links too flashy. One reviewer flagged the bezel lock mechanism as flimsy and inconvenient, and another noted a strap's shape made it less comfortable on smaller wrists. The Yema Superman Steel CMM.10 features Grade A Super-LumiNova and the CMM.10 automatic movement with a 70-hour power reserve, regulated to +5/-3 seconds per day. Overall, owners and reviewers rate the Yema Superman Steel CMM.10 highly for its refined finishing and comfortable wearability at its price point.
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.
