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

The Glycine Combat Sub is widely praised for its excellent value, thin case height (ranging from 10.4mm to 10.8mm), and comfortable wearability due to downward-curving lugs, with owners noting its quality and finishing punch well above its price point. Reviewers and owners consistently highlight its smooth bezel action, crisp font, and a unique aesthetic that avoids being a direct homage. However, criticisms include sub-par lume that is difficult to read in low light and an inconsistent power reserve, with some owners suggesting it may require servicing. Opinions are split on the 42mm size, with some finding it perfect and others preferring a smaller variant. On balance, owners and reviewers rate the Glycine Combat Sub highly for its exceptional thinness and quality finishing at its price point.
