What people say

Owners + reviewers, side by side

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

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.

NOMOS Glashütte Tangomat ruthenium

Owners widely praise the NOMOS Glashütte Tangomat ruthenium for its Glashütte watchmaking and Bauhaus design, with one owner noting accuracy at +2 seconds/day and a 43-hour power reserve. Some owners find the Tangomat thicker than other models, with case proportions that may not suit its sharp design, and one owner expressed a preference for newer movements over the older Epsilon automatic. Overall, owners value the NOMOS Glashütte Tangomat ruthenium for its precise timekeeping and design ethos.
