Sugess Seakors Tourbillon SE8007vsYema Skin Diver CMM.20

Owners widely praise the Sugess Seakors Tourbillon for its attractive dial and case finishing, along with the value offered by its functional flying tourbillon. One owner reports the Seagull ST8007 movement is reliable, running at -2s/day or +5s/day. However, the 24-hour complication is considered questionable, and some dust and oil are visible under magnification. With 5ATM water resistance and no lume, it is not suited for demanding activities. On balance, owners rate the Sugess Seakors Tourbillon highly for its impressive tourbillon complication and design 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.
