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.

Glycine Combat Sub

Owners widely praise the Glycine Combat Sub for its exceptional thinness, with many noting its 10.4mm to 10.8mm profile for a diver, perfect proportions, and solid build quality that offers significant value, especially at discounted prices. Its unique aesthetic is appreciated for avoiding homage looks, and the lug design contributes to a smaller perceived wear size despite its 42mm case. Some owners report an inconsistent power reserve and sub-par lume that can be difficult to read at night, while one owner noted a slightly off-color lume pip on the chapter ring. Overall, owners rate the Glycine Combat Sub highly for its refined feel, slim profile, and value proposition.
