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 Sea 1965 Heritage Diver's Watch PADI Special Edition

The Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition is praised for its attractive emerald green sunburst dial with gold accents and its comfortable wearability. Owners note the dial looks gorgeous in the right light, and some find it fits better than other models. The watch features a 40mm steel case, a domed sapphire crystal, and 300m water resistance, powered by the 6R55 movement with a 72-hour power reserve. However, some find the watch wears top-heavy due to its density and case design, and the bracelet clasp is criticized for stamped parts and limited micro-adjustment. The retail price of €1,700 is considered high by some, with sales recommended. Overall, owners and reviewers appreciate the dial's beauty and the watch's comfortable fit, despite some reservations about its weight distribution and bracelet clasp.
