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 Hull Riviera

Owners praise the Spinnaker Hull Riviera's build quality, highlighting its milled clasp, solid links, and effective anti-reflective coating on the sapphire crystal. The watch features a sandwich dial with Superluminova, measures 42mm in diameter, 12mm thick with a 48mm lug-to-lug span, and uses a Seiko NH35 movement. Accuracy is reported as excellent, with one owner noting a gain of only +2 seconds over seven days. The crystal is noted as being fused to the case, leading to a repair quote of $198 for a cracked crystal, a cost considered excessive by some owners relative to the watch's price. Lume is considered mediocre, and some would have preferred a 4Hz movement. Overall, owners rate the Spinnaker Hull Riviera highly for its robust build and impressive accuracy at its price point.
