Wolbrook Skindiver II ProfessionalvsYema Skin Diver CMM.20

Owners widely praise the Wolbrook Skindiver II Professional for its comfortable wearability, long-lasting lume, and attractive dial designs, with some appreciating the quartz accuracy and smooth sweeping second hand. The watch features a 40mm diameter, a well-weighted 120-click unidirectional countdown bezel with a BGW9 lumed triangle, and a shock-resistant HexapleX case architecture. It is powered by either a Miyota 9015 or 8315 movement, with the latter adjusted in France to ±15 seconds per day and offering a 60-hour power reserve. Some owners find the 20mm strap potentially problematic and note it wears like a 42mm watch despite its 40mm case size. One reviewer expressed disappointment in hand color matching, poor lume, bezel wobble, and the watch sitting high on its strap, ultimately not recommending it.

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.
