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.

Sugess Tourbillon Master S454

Owners widely praise the Sugess Tourbillon Master S454 for its attractive dial finishing, sharp case edges, and the visual appeal of its genuine tourbillon, especially considering its price point. Specific strengths highlighted include a delicate 38mm size with 11.5mm thickness and a crisp winding feel. However, multiple owners note accuracy issues, with figures ranging from +6 to +11 seconds per day and one report of -12 seconds per day. Concerns are also raised about the movement's finishing upon close inspection, the lack of internal anti-reflective coating causing reflections, a small crown that makes winding cumbersome, and potential long-term durability and serviceability challenges. The 24-hour complication is not independently adjustable, and water resistance is limited to 50m. Overall, owners rate the Sugess Tourbillon Master S454 highly for its impressive tourbillon and finishing at the price, despite some noted accuracy and finishing caveats.

From video reviewers

The value proposition of a functional tourbillon movement under $600 is a significant strength. Reviewers noted issues with the bracelet and wearability.
