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 S437

Owners widely praise the Sugess MoonPhase Master S437 for its striking dial, often described as deep blue or aventurine, and its value, with prices around $171-$175. The Seagull ST1908 movement is noted as accurate, with one owner reporting +3 seconds over 18 hours and another +7 seconds daily, and its hand-winding action is smooth. However, the watch's thickness, potentially over 13mm, is a concern for some as a dress watch, and the long lugs may pose a fit issue on smaller wrists. A potential design flaw in the moonphase window, showing two phases simultaneously, is flagged as a deal-breaker by some. The included leather straps are considered stiff and uncomfortable, and the domed sapphire crystal lacks AR coating, leading to reflections. On balance, owners rate the Sugess MoonPhase Master S437 highly for its stunning dial and value, despite some fit and finishing concerns.

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.
