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 Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional value, thin profile, and solid build quality, often noting its finishing and wearability as superior for its price point. Reviewers consistently flag its slim case, with measurements around 10.4mm to 10.8mm, and appreciate its non-homage design and comfortable lug curvature. Accuracy figures vary, with one owner reporting only 2 seconds per day loss, while another notes their Sellita SW200 movement runs at +6 to +9 seconds per day. Some owners report inconsistent power reserve not reaching the advertised 42 hours and find the lume sub-par for nighttime legibility. A few also mention sharp bracelet edges and a potentially short bracelet for larger wrists, and one owner dislikes the "COMBAT" text on the dial. On balance, owners and reviewers rate the Glycine Combat Sub Sport highly for its impressive thinness and value as a Swiss automatic diver.
