What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Maen Manhattan 三七

Owners are 100% satisfied with the Maen Manhattan 三七's looks and finishing quality, finding it super comfortable. Reviewers praise its modest dimensions, appealing case profile, and dial finishing with a vertical Côtes de Genève pattern, though one owner notes the dial color is deceptively different from website images. The Maen Manhattan 三七 features a thin 7.1mm case and 100m water resistance with a screw-down crown, utilizing a manual-wind movement with a two-day power reserve, while another reviewer points to a different movement with an average accuracy deviation of +/- 12 seconds per day and a 40-hour power reserve. On balance, owners and reviewers rate the Maen Manhattan 三七 highly for its finishing and comfortable wearability at its price point.
