What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Mark Time Watches M 6

The Mark Time Watches M 6 features a 39mm case with a deep black dial that gives the hands a floating appearance, and the second hand extends to the edge of the dial. Owners appreciate the absence of a ghost date position, a minimalist logo, and actual bezel screws. However, some find telling time to the nearest minute or two is challenging. Overall, owners value the M 6 for its thoughtful design elements like the full-length second hand and functional bezel screws.

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.
