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.

KUOE ROYAL SMITH 90-006

Owners widely praise the KUOE ROYAL SMITH 90-006 for its visual appeal and sapphire crystal with AR coating. The watch functions correctly and keeps time at approximately +5 seconds per day on the wrist, powered by a Miyota 9039 movement. On balance, owners value the watch's aesthetics and specifications, though some question its overall value proposition.

From video reviewers

The watch's unique blend of modern and retro elements is a notable strength, with a textured ivory waffle dial and Breguet numerals giving it the look of a vintage watch from the 1950s and 1960s. A potential drawback is the ~$770 USD price point, which is significant for a microbrand. Reviewers disagree on the movement's accuracy, with one reviewer noting it is noisy and another describing it as a "Japanese-manufactured high beat premium automatic movement".
