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.

Baltic HMS 003

The Baltic HMS 003 is widely praised for its vintage charm, featuring a three-dimensional sector dial with a deep blue and gilt color scheme, heat-treated blue hands, and varied textures. Owners and reviewers highlight its 36.5mm case size, high-dome crystal, and Beads of Rice bracelet as particularly appealing. The Miyota 8315 automatic movement provides a 60-hour power reserve and stop-seconds function. One owner notes the domed hesalite crystal is prone to scratching. Overall, owners and reviewers rate the Baltic HMS 003 highly for its unbelievably gorgeous design and vintage aesthetic at its price point.

From video reviewers

The Baltic HMS 003's downsized case to 36.5mm is a significant strength, making it a genuinely vintage-sized watch. A notable trade-off is the relatively thin lume on the watch, which is 'not the brightest' but still functional. Reviewers disagree on the watch's overall build quality, with one reviewer stating it has "better finishing" than the previous model, while another reviewer notes that specific details about the watch's finishing, indexes, or overall build quality are not mentioned.
