Nivada Grenchen Antarctic 35mm AutomaticvsYema Skin Diver CMM.20

The Nivada Grenchen Antarctic 35mm Automatic is lauded for its authentic vintage proportions, slim 7mm case profile, and elegant, understated design, with reviewers highlighting its charm, versatility, and friendly price. Owners and reviewers praise its comfortable 35mm size and long lugs for good wrist presence, manual-wind Landeron 21 movement, and applied indices. Some owners note an odd transition between the fully high-polished case and the dull outer links of the Beads of Rice bracelet. Water resistance is limited to 50 meters due to the push-pull crown, and lume is not particularly strong, with one reviewer finding the beige lume on a white dial a slight mismatch. The 36-hour power reserve is also noted. Overall, owners and reviewers rate the Nivada Grenchen Antarctic 35mm Automatic highly for its faithful vintage recreation and value 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.
