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.

Yema Superman Bronze CMM.10

The Yema Superman Bronze CMM.10 is praised for its neo-vintage dive watch aesthetic, featuring a bronze case with brushed and polished finishing and a gradient blue sandwich dial with Super-LumiNova. It is powered by the in-house CMM.10 automatic movement, which offers a 70-hour power reserve and chronometric precision rated at -3/+5 seconds per day. The watch is available in 39mm and 41mm case sizes and comes on FKM Viton rubber straps. It was offered at a pre-order price of €999. Overall, reviewers highlight the Yema Superman Bronze CMM.10 as a refined neo-vintage dive watch with a capable in-house movement and attractive finishing.
