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.

Zelos Swordfish 3

Owners widely praise the Zelos Swordfish 3 for its strong value, with reviewers highlighting the textured sandwich dial, Seiko NH35 movement, 200m water resistance, and surprisingly good bracelet. The titanium construction is noted for making the watch compact and comfortable, weighing 117g. Some owners find the dimensions fine on paper and based on experience with other models. One reviewer flagged that legibility can suffer in bright light and bracelet edges are sharp. Overall, owners and reviewers rate the Zelos Swordfish 3 highly for its incredible value and fun design, particularly with unique dial options.
