What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Longines CONQUEST

Owners and reviewers widely praise the Longines CONQUEST for its high-quality finishing, versatile design, and exceptional value, with many highlighting its comfortable wearability and solid build. Accuracy figures are generally positive, with one owner reporting +1/+2 seconds per day. However, several owners note that the bracelet lacks micro-adjustment, which can affect fit, and some find the lume to be weak or inconsistently applied across variants. One owner also mentioned the crown rubbing against the wrist. On balance, owners and reviewers rate the Longines CONQUEST highly for its blend of elegant design and robust build at an accessible price point.

From video reviewers

The perfectly balanced case size is a key strength of the Longines Conquest. A notable weakness is the somewhat lacking lume brightness. Reviewers disagree on the ideal case size, with one preferring 38mm and the other 39mm.

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.
