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.

Hamilton Jazzmaster Power Reserve Auto

The Hamilton Jazzmaster Power Reserve Auto is praised by owners and reviewers for its value and history, featuring an 80-hour power reserve caliber H-13 movement. Owners note poor lume, easily scratched polished bezels, and a mineral crystal on the movement display. One owner suggests the 80-hour power reserve is difficult to achieve without manual winding. On balance, owners and reviewers rate the Hamilton Jazzmaster Power Reserve Auto well for its value and history, despite noted drawbacks in finishing and crystal material.
