Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Longines Flagship Heritage Moonphase is widely praised for its elegant aesthetic, balanced midnight blue dial with dauphine hands and wedge indices, and the L899.5 movement's 72-hour power reserve. Owners appreciate its value, classy integrated moonphase complication with a night blue background and shiny silver stars, and comfortable 38.5mm case size with good finishing, fitting well on smaller wrists. However, reviewers and owners note its minimal 30-meter water resistance, a 3 o'clock crown that appears undersized, and a thickness of 12.4mm, which some find hinders its dress watch suitability and ability to slip under a cuff, though others find it wearable. Some also consider the design overly traditional and the rehaut depth excessive. On balance, owners and reviewers rate the Longines Flagship Heritage Moonphase highly for its elegant design and value proposition 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.
