Sugess Tourbillon Master SU8001vsYema Skin Diver CMM.20

Owners widely praise the Sugess Tourbillon Master for its accessible tourbillon complication and value, with one owner noting an initial accuracy of +2 seconds per day. However, community feedback flags a winding stem that feels flimsy and straps that are considered poor, featuring a comically large buckle. Some owners report a degradation in accuracy to around -20 seconds per day after a month, and the steel case edges are described as rounded with the material proving soft and prone to scratching. On balance, owners view the Sugess Tourbillon Master as a remarkable value for its tourbillon feature, despite concerns regarding strap quality and long-term material durability.

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.
