What people say

Owners + reviewers, side by side

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

Pinion Pure Steel

Owners widely praise the Pinion Pure Steel's balanced 38mm case size and 44mm lug-to-lug, fitting most wrists well. The dial is described as clear and essential, though reviewers note the lack of a minute track makes precise minute setting difficult. Accuracy is regulated in-house to +/- 5 to +/- 15 seconds per day. Some commenters found the white straps on featured watches to look "horrible." Overall, owners and reviewers appreciate the Pinion Pure Steel for its well-proportioned case and essential dial design.

Yema Superman Tourbillon CMM.31 Limited Edition

Owners praise the Yema Superman Tourbillon CMM.31 Limited Edition as an incredible and crazy watch, appreciating its unnecessary tourbillon complication and impressive specifications at a remarkable price point. The titanium construction contributes to comfort despite the 43mm case size. One reviewer notes the bracelet clasp's extension system is somewhat crude. On balance, owners and reviewers rate the Yema Superman Tourbillon CMM.31 Limited Edition highly for its compelling tourbillon feature at an accessible price.
