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 Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
