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 S426

Owners widely praise the Sugess MoonPhase Master S426 for its sapphire crystal, well-finished stainless steel case, and the Seagull ST2153 automatic movement, which offers hacking and manual winding. The watch features a real moonphase complication, power reserve indicator, and date function, all for approximately $200. Reviewers highlight the guilloche dial detailing and the ST2155 movement, an ETA clone, noting its true moonphase complication. Overall, owners rate the Sugess MoonPhase Master S426 highly for its impressive complications and finishing at its price point.

Yema Navygraf Marine Nationale Quartz

Owners praise the Yema Navygraf Marine Nationale Quartz for its well-made case, clean legible dial, and comfortable 39mm size, with one noting its thin profile for 300m water resistance. Accuracy figures vary, with one owner reporting +6 seconds per day and another seeing it keep within COSC time. Minor criticisms include a steel bracelet with a slight rattle and sharp edges, bent bracelet pins, and in one instance, crooked dial printing. On balance, owners find the Yema Navygraf Marine Nationale Quartz offers good value and wearability, with its French design and thinner case being key highlights.
