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.

Maen Manhattan 40

Owners appreciate the Maen Manhattan 40's thin case and unique dial, with some finding its proportions too large for smaller wrists. One owner noted a snagging crown and difficult winding action. Accuracy figures vary, with one owner reporting +18s/d to +24s/d on the 37mm version, while another owner of the 40mm model did not specify accuracy. On balance, owners and reviewers find the Maen Manhattan 40 to be a good value, with its thinness and dial finishing being key strengths.
