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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
