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.

Oak & Oscar The Humboldt 12-hr

Oak & Oscar The Humboldt 12-hr owners widely praise its comfortable, solid bracelet with screw links and tight end-link fit, along with its awesome sandwich dial featuring superb grain and crisp details. The 12-hour bezel is noted as excellent for tracking a second time zone, and the orange second hand adds a nice pop. One owner reports the watch has outstanding quality and a perfect fit on smaller wrists, while another notes its legibility and great presence on various straps. A reviewer describes it as a 40mm stainless steel tool watch with a matte, brushed finish and a sandwich dial, powered by an ETA 2892-A2 movement with a 42-hour power reserve. Some in the line report the lume could be brighter. On balance, owners and reviewers rate Oak & Oscar The Humboldt 12-hr highly for its build quality and versatile tool-watch design.
