What people say

Owners + reviewers, side by side

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

AVI-8 Flyboy Airmaster GMT Automatic

Owners widely praise the AVI-8 Flyboy Airmaster GMT Automatic for its robust build quality, intricate three-timezone function, and crisp dial texture. The watch is noted for its wearable 41mm case size and 48.5mm lug-to-lug, with an internally positioned GMT complication that maintains a clean dial appearance. Some owners report the stock leather strap feels cheap and limits strap changing options. On balance, owners rate the AVI-8 Flyboy Airmaster GMT Automatic highly for its solid finishing and value, particularly highlighting the dial's depth and texture.

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.
