Grand Seiko SBGH263vsYema Skin Diver CMM.20

The Grand Seiko SBGH263 is praised for its excellent finishing for the price, with reviewers comparing it to Jaeger-LeCoultre. Owners and reviewers highlight the stunning 'Shironeri' dial and gold hands/numerals, and the 39.5mm case size is considered a perfect fit, referencing vintage Grand Seiko models. The watch features a 55-hour power reserve from its 36,000 BPH movement, though one reviewer felt the date aperture was unnecessary. On balance, owners and reviewers rate the Grand Seiko SBGH263 highly for its exceptional dial and finishing at its price point.

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.
