Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Longines MASTER COLLECTION CHRONO MOONPHASE for its mesmerizing dial and value, offering numerous complications at its price point. However, its 3 bar water resistance limits wearability, and some find the dial busy with the chronograph hour pointer obscuring the moonphase. One owner noted it is a "thick boi" and the blue is less vibrant than pictured, while another mentioned scuffs on the case and discrepancies with the rotor weight and column wheel compared to the website. The consensus is that the Longines MASTER COLLECTION CHRONO MOONPHASE is a gorgeous, high-horology offering for its price, despite some functional limitations and aesthetic critiques.
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.
