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 widely praise the Longines CONQUEST for its high-quality finishing, excellent value, and versatile design, with many citing the L888.5 movement and 72-hour power reserve as key strengths. The watch is frequently noted for its comfortable bracelet and attractive dials, offering comparable quality to more expensive alternatives. However, several owners and reviewers point out the lack of micro-adjustment on the bracelet clasp as a significant drawback, with some also noting the polished surfaces are prone to micro-scratches and the lume is inconsistent across variants, with only some models featuring lumed hands. On balance, owners and reviewers rate the Longines CONQUEST highly for its impressive finishing and value proposition, particularly its robust movement and versatile wearability.

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.
