Nivada Grenchen F77 MK1vsYema Skin Diver CMM.20

Owners widely praise the Nivada Grenchen F77 MK1 for its vintage charm, Genta-inspired design with unique character, and comfortable 37-38mm wearability on average wrists, highlighting its legible basket-weave dial and solid case build with excellent crown grip. The integrated bracelet's connection to the case is noted to increase effective lug-to-lug distance, and one owner criticizes the crown action as stiff and gritty. The Soprod P024 movement provides a 38-hour power reserve. On balance, owners and reviewers find the Nivada Grenchen F77 MK1 a compelling value proposition due to its distinctive dial and overall build quality, despite some reservations about its winding feel and price.

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.
