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.

Seiko Prospex LX line

Owners widely report the Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.
