What people say

Owners + reviewers, side by side

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

Citizen Promaster Diver Automatic

Owners widely praise the Citizen Promaster Diver Automatic for its lightweight titanium build, comfortable wear, and good specifications at its price point, with one owner highlighting its accuracy and dynamic dial made from recycled materials. Some users find the bezel action spongy and the bracelet subpar, while others note the overall finish is basic due to the brushed titanium. A reviewer also points out a preference for sapphire crystal and ceramic bezel inserts. On balance, owners rate the Citizen Promaster Diver Automatic highly for its value proposition as an affordable, lightweight, and accurate dive watch.

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.
