Grand Seiko SBGH289vsYema Skin Diver CMM.20

The Grand Seiko SBGH289 is praised for its legible blue dial, strong Lumibrite, and the accurate Hi-Beat Caliber 9S85 movement. Reviewers note its bright initial lume glow, though its longevity is questioned compared to other models. The watch features Grand Seiko's Super-Hard Coating for scratch resistance and retails for €7,200. Overall, reviewers highlight the SBGH289's appealing aesthetics and robust movement as key strengths.

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.
