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.

Tissot PR 100

Owners widely praise the Tissot PR 100 for its excellent value, with specific mentions of its sapphire crystal, 100m water resistance, and the 80-hour power reserve of its Powermatic 80 movement. Reviewers and owners consistently highlight its pleasing winding action and strong lume. Accuracy figures for the Powermatic 80 COSC variants are reported as -2 seconds per day or +/- 1-2 seconds per day. Some owners note that the crystal attracts fingerprints and that the black finish on some bracelets can wear off after extended daily use. A single owner of a quartz model experienced a recurring issue where the watch stopped for periods weekly, which was not resolved by a battery replacement. Overall, owners and reviewers rate the Tissot PR 100 highly for its exceptional value and robust features, particularly its durable construction and reliable movements.
