What people say

Owners + reviewers, side by side

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

Longines MASTER COLLECTION

Owners and reviewers widely praise the Longines Master Collection for its excellent finishing and value, with specific mentions of beautiful dials featuring engraved Breguet numerals and blued hands. The movement offers a 72-hour power reserve, and the classical design is noted as versatile. Some owners report the bracelet lacks sufficient micro-adjustment options for a precise fit, and one owner experienced a broken moon phase setting mechanism requiring service. The Master Collection Annual Calendar has 30m water resistance, considered light by one reviewer. Overall, the consensus is that owners and reviewers rate the Longines Master Collection highly for its exceptional value and refined finishing.

From video reviewers

The watch has a strong wrist presence and comfort. The movement accuracy is also a notable feature, delivering luxury value 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.
