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 PRX UFO Robot Grendizer

The Tissot PRX UFO Robot Grendizer is noted for its unique sunburst blue dial featuring an embossed Grendizer bust, which, along with the hands and indices, offers yellow-green and blue-green luminescence respectively, while the seconds hand is shaped like Grendizer's weapon. This special edition utilizes the Powermatic 80 movement, providing an 80-hour power reserve, and comes in distinctive Spazer spaceship packaging. Reviewers suggest the €120 price premium for these thematic elements and packaging may only appeal to fans of the manga. Overall, reviewers consider the Tissot PRX UFO Robot Grendizer a clever, niche special edition that avoids excessive gimmickry, particularly appealing to manga enthusiasts.
