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.

DOXA SUB 600T

The DOXA SUB 600T is widely praised for its purposeful, angular, and unique 80s-inspired aesthetic, available in a variety of saturated dial colors and bezel options. Reviewers and owners highlight its tactile bezel action, grippy crown, and improved lume compared to previous models. However, multiple sources identify the excessively tall and blocky case back as a significant shortcoming, leading to a top-heavy feel and tendency to shift on the wrist, with some owners questioning its wearability on smaller wrists. The Sellita SW200-1 movement's 38-hour power reserve is also noted as underwhelming for the price point, and strap/clasp adjustments can be challenging for a comfortable fit. On balance, owners and reviewers appreciate the DOXA SUB 600T's distinctive tool watch character and vibrant colorways, despite the noted wearability and movement power reserve concerns.

From video reviewers

The DOXA SUB 600T's angular case design and robust brushed finish are notable features. The watch's price point is relatively high compared to its competitors. Reviewers disagree on the watch's water resistance, with one reviewer noting it's somewhat limited, while the other reviewer doesn't mention this.
