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.

Studio Underd0g Salmon

Owners widely praise the Studio Underd0g Salmon for its unique, two-layered dial inspired by salmon skin, featuring a radially brushed metallic orange-pink lower part and a coarse, silvery dégradé shimmer upper part. The watch is powered by a decorated Swiss mono pusher movement with silky smooth winding, blued screws, and anthracite bridges, which one owner finds impressive. Accuracy is reported at ±5 seconds per day. Some owners find the £1700-£1800 price point difficult, especially given styling similarities to previous models. Overall, owners and reviewers rate the Studio Underd0g Salmon highly for its distinctive dial design and well-finished, smooth-winding monopusher movement.
