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 S389

Owners widely praise the Sugess MoonPhase Master S389 for its beautiful dial and glowing moonphase, with some finding it a stunner that exceeds expectations and a bargain for the price. However, reviewers and owners alike flag rotor noise and thickness as potential drawbacks, and one owner reported receiving a defective unit. Accuracy is reported at -6 seconds per day, and while the dial features applied markers and polished hands, the movement finishing is noted as rough under magnification. Overall, owners rate the Sugess MoonPhase Master S389 highly for its aesthetic appeal and value, despite some concerns regarding rotor noise and build quality consistency.

Massena LAB Uni-Racer

The Massena LAB Uni-Racer is praised for its refined vintage chronograph aesthetic, featuring a 39mm case with unique horizontal finishing, a GPHG-nominated hand-wound Sellita SW510 M movement, and a sector dial with a "big eye" counter. Owners and reviewers highlight its period-perfect Super-LumiNova and snailing on recessed registers, all supported by a 58-hour power reserve and 50m water resistance. On balance, owners and reviewers rate the Massena LAB Uni-Racer highly for its authentic vintage design and refined execution at its price point.
