What people say

Owners + reviewers, side by side

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

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.

Seestern S450 Ocean Star

Owners widely praise the Seestern S450 Ocean Star's Yachtmaster-style case and flawless bracelet finishing, with one owner noting the ST2130 movement keeps good time. The bezel action is described as having individual notches but feeling like a friction bezel, while another owner flags the bezel and crown action as smooth with perfect alignment. Lume is a point of contention, with one source describing it as a nice cool blue with ice-white application, while others note it as weak or not matching Prospex standards, despite using BGW-9. The watch is considered a "big boy" ideal for larger wrists (19cm+), potentially too large for 17cm wrists due to its size and non-tapering bracelet. Overall, owners rate the Seestern S450 Ocean Star highly for its build quality and finishing at the price point, despite some reservations about its size and lume intensity.
