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.

NOMOS Glashütte Tetra 27 duo

Owners widely praise the NOMOS Glashütte Tetra 27 duo for its ideal small and light wearing dimensions, beautiful dial that shifts with lighting, and gorgeous blued hands, with some finding its 27mm size perfect for vintage preferences. The watch is noted for its precise, Art Deco-inspired design and good finishing. However, some owners and reviewers consider the 27.5mm size too small, labeling it a women's watch, though others find it unisex and note its square shape can make it wear larger. One owner flags the buckle as disappointingly generic and the grey suede strap as prone to getting dirty. Overall, owners and reviewers highly regard the NOMOS Glashütte Tetra 27 duo for its elegant design and comfortable wearability at its price point.
