Glycine Combat Sub SportvsYema Skin Diver Slim CMM.20

Owners widely praise the Glycine Combat Sub Sport for its exceptional thinness, with multiple sources noting profiles between 10.4mm and 11mm, comfortable wearability on a variety of wrist sizes due to its proportions and contoured lugs, and its value, especially when found under $400. Some owners highlight its refined finishing and unique, non-homage design, while others appreciate its ruggedness and durability, with one noting PVD coating remained flawless after three years of heavy use. Accuracy figures range from excellent, with one owner reporting only 2 seconds lost per day, to inconsistent power reserve and occasional reported issues with the movement and stem. The lume is described as subpar by some, though one owner found it marginally better than a Seiko SKX007. Reservations are occasionally raised regarding warranty service and the use of folded end links on the bracelet.

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.
