What people say

Owners + reviewers, side by side

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

Lorca MODEL No.1 GMT

Owners and reviewers widely praise the Lorca MODEL No.1 GMT for its 36mm size and 11.2mm thinness, vintage-inspired design, and crisp finishing. The champagne sunburst dial and integrated bracelet are frequently highlighted as attractive elements. Some owners note the bezel font as a detractor, and a reviewer points out the lume is insignificant. The watch uses a caller GMT movement, and one owner finds the small crown impractical to manipulate. Accuracy is reported as within +/- 4 seconds per day, and it features 20 ATM water resistance. Overall, owners and reviewers appreciate the Lorca MODEL No.1 GMT for its refined design and compact dimensions, though some question its value proposition for an emerging brand.

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.
