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 Marinemaster Marinemaster 1965 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.
