Praesidus Arctic FieldvsYema Skin Diver CMM.20

The Praesidus Arctic Field is noted for its good readability and a faux patina that suits its style, with a blue anti-reflective coating on the sapphire crystal being a welcome detail. One reviewer highlights its 38mm titanium case with a brushed finish and 11.35mm thickness as well-crafted and elegant. On balance, reviewers find the Praesidus Arctic Field to be a readable and well-finished field watch.

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.
