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.

Spinnaker Bradner GMT

The Spinnaker Bradner GMT is praised for its awesome lume and comfortable wearability, with one owner noting the rubber strap is very comfortable and the beads of rice bracelet fits well on smaller wrists. Some find its 15mm thickness and bold colorway may not appeal to everyone, and one owner views it as more of a casual GMT with tool-watch styling than a diver. Overall, owners rate the Spinnaker Bradner GMT highly for its value and comfortable wearability.
