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.

Zelos Skyraider 40 Skeleton

The Zelos Skyraider 40 Skeleton is noted for its skeletonized dial and the use of BGW9 and C3 Super-LumiNova for legibility. It is powered by a manual-wind ETA 6498 movement, offering a 44-hour power reserve. On balance, the Zelos Skyraider 40 Skeleton is seen as a cool-looking option, though availability is a factor.
