What people say

Owners + reviewers, side by side

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

HELM Miyako

HELM Miyako owners widely praise its exceptional value and quality, with multiple reports highlighting its stunning appearance and dial details. The watch is noted for its excellent accuracy, with figures around +1.5 to +2 seconds per day. One owner found the HELM Miyako to be tough and versatile, fitting well on a 6.6-inch wrist. Overall, owners consider the HELM Miyako an amazing value and a great watch, worth the wait for its availability.

Yema Skin Diver Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.
