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 Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.
