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.

Lorier Astra Cosmic Blue

Owners widely praise the Lorier Astra Cosmic Blue for its beautiful, vintage 1960s aesthetic and comfortable 36mm size, fitting well even after initial adjustment. Some community members appreciate its clean lines and attractive design, though a few wish for more variation in the brand's case and bracelet designs across its models. Overall, owners rate the Lorier Astra Cosmic Blue highly for its stunning, dressy vintage appeal and wearability.
