What people say

Owners + reviewers, side by side

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

Halios Seaforth IV

Owners widely praise the Halios Sunburst Blue for its perfect 40mm size, stunning sunburst dial, and excellent lume, with one owner calling it Halios's best effort and a potential "Omega AT killer." The ETA 2824 movement is noted as running smoothly, and the watch is considered a great value with strong resale. Some owners desire larger sizes or different dial colors, and one reviewer found the Sinn 556i more versatile. The sapphire bezel is described as tall and flat, which is a point of contention for some. Overall, owners rate the Halios Sunburst Blue highly for its design, size, and value.

From video reviewers

The sunburst blue dial is a standout feature. Limited water resistance is a shared concern.

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.
