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.

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.

Marathon Steel Navigator SSNAV Auto

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance.

One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.
