What people say

Owners + reviewers, side by side

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

Seiko DressKX

The Seiko 5 Sports SKX series is widely praised as a gateway mechanical watch offering exceptional value and iconic status, with owners appreciating its ruggedness, tool-like authenticity, and moddability. Many owners report the 4R36/NH36 movement achieves accuracy of +/-5 to 10 seconds per day, far exceeding its stated specifications, and the stock Jubilee bracelet is noted as surprisingly comfortable. Some owners find the Seiko 5 Sports SKX series bulky and less aesthetically pleasing than newer models, with others noting its specifications lag behind contemporary watches. The Seiko 5 Sports SKX series is considered a decent watch, especially when found under £200, but it's not the serious tool watch the original SKX was, lacking a screw-down crown, bezel pip, and ISO rating. Overall, owners rate the Seiko 5 Sports SKX series highly for its iconic dive watch lineage and excellent value at the price point.

From video reviewers

The clean dial and versatile dressy look are praised. The overall thickness and handset are points of contention.

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.
