Pinion Pure BronzevsYema Skin Diver CMM.20

The Pinion Pure Bronze is lauded for its refreshing design, featuring a beautiful layered dial with applied numerals and luminous indexes. Reviewers praise its satisfying manual-winding action from the Unitas 6498 movement, which offers a 45-hour power reserve. One reviewer suggested a satin finish for the crown to match the case back and buckle. Overall, reviewers rate the Pinion Pure Bronze highly for its unique bronze case that patinates over time and its clear, subtly finished dial.

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.
