What people say

Owners + reviewers, side by side

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

Sugess MoonPhase Master S394

Owners widely praise the Sugess MoonPhase Master S394 for its impressive value, offering multiple complications at a sub-$200 price point, with one owner highlighting its deep blue dial and applied markers. While one owner finds the 14mm thickness acceptable and wearable, another notes the included straps are subpar and the movement finishing is rough under magnification. The long lugs can also create a noticeable gap with the strap. On balance, owners rate the Sugess MoonPhase Master S394 highly for the significant complications and aesthetic appeal it delivers at its accessible price.

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.
