What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fortis Marinemaster M-44

The Fortis Marinemaster M-44 is praised for its excellent build quality and wearability, featuring a highly legible dial and a COSC-certified Kenissi-based movement that ran at 0 seconds per day. Owners appreciate its 70-hour power reserve and the inclusion of multiple straps and a deployant buckle, noting its gorgeous appearance and great wrist presence. A minor point raised is the 21mm lug width, with a wish for it to be 22mm. The Fortis Marinemaster M-44 is priced at $4,150. Overall, owners and reviewers rate the Fortis Marinemaster M-44 highly for its robust specifications and comfortable wearability at its price point.

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.
