What people say

Owners + reviewers, side by side

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

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.

Yema Navygraf CMM.10

Owners widely report quality control concerns and suspect craftsmanship with the Yema Navygraf, with one user noting crooked text. A reviewer praised the Slim CMM.20 Limited Edition for its stylish, slim profile and classy finishing on a black lacquered enamel dial, though the audible micro-rotor spinning at its price point was a surprise. On balance, the consensus is that while the Yema Navygraf offers a stylish design, potential buyers should be aware of reported quality control issues.
