Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Longines MASTER COLLECTION CHRONO MOONPHASE for its beautiful and legible dial, offering significant complications for its value. Accuracy figures vary, with one owner reporting +8 seconds per day and another stating it is their most accurate watch. Some find the chronograph hour hand placement inconvenient, and the date hand can occasionally overlap the hour hand. The watch is noted as being thick, typical of Valjoux-based chronographs, and its 3 bar water resistance limits it to less demanding environments. One owner observed scuffs on the case of their example, and another found the blue on the band and numerals less vibrant than pictured. Overall, owners rate the Longines MASTER COLLECTION CHRONO MOONPHASE highly for its impressive complications and aesthetic appeal 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 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.
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.
