What people say

Owners + reviewers, side by side

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

Marathon Arctic OSAR 41mm Automatic

The Marathon Arctic OSAR 41mm Automatic is noted for its comfortable wearability on wrists under 7 inches, with one owner finding the 41mm size perfect. Accuracy observations vary, with one owner reporting a consistent +1 second per day and another noting -20 seconds per day. The watch features a Sellita automatic movement and has dimensions of 14mm thickness and a 48mm lug-to-lug. Overall, owners appreciate the Marathon Arctic OSAR 41mm Automatic for its comfortable fit and Marathon's overall appeal.

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.
