What people say

Owners + reviewers, side by side

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

Seestern Sub 300 V4

Owners widely praise the Seestern Sub 300 V4 for its terrific fit and finish and surprising little touches at its $179 price, noting top-notch case, dial, bezel, and crystal. The bracelet is considered nice enough for the price point, and the watch is powered by the solid and reliable Seiko NH35 movement. Some owners report that the polished sides of the case show signs of wear. Overall, owners rate the Seestern Sub 300 V4 highly for its excellent case, dial, and bezel finishing at the price.

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.
