What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.

Sugess MoonPhase Master SU2528

Owners widely praise the Sugess MoonPhase Master SU2528 for its visually stunning and glittery aventurine dial, considered exceptional value for its price, with some noting smooth hand-winding and good case polishing. Accuracy varies, with reports ranging from +3 seconds per day to -6 seconds per day, and one owner experienced a stuttering movement in a previous unit. Some find the watch too thick for a dress watch, the rotor unusually loud, and the 21mm lug width unorthodox, while the moonphase complication's accuracy is questioned by one owner due to a potential dial cut flaw. Overall, owners rate the Sugess MoonPhase Master SU2528 highly for its gorgeous aventurine dial and impressive complications at an accessible price point.
