What people say

Owners + reviewers, side by side

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

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.

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.
