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.

From video reviewers

The watch's lume is praised as a significant strength. Reviewers noted issues with the watch's finishing.

Seiko 5 Sports Field series

The Seiko 5 Sports Field series is praised for its value, offering an accessible explorer-style watch with a GMT complication and excellent legibility thanks to LumiBrite on the dial and bezel. The watches feature a 41mm stainless steel case, 100m water resistance, and are powered by either the 4R36 or 4R34 movement, both with a 41-hour power reserve. One reviewer notes the inclusion of a compass bezel with a lumed pearl and fully lumed Arabic numerals on the dial for the non-GMT models. Overall, reviewers consider the Seiko 5 Sports Field GMT models good value under 500 euros.
