What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Longines MASTER COLLECTION

The Longines Master Collection is widely praised for its excellent value and refined design, with owners and reviewers highlighting its beautiful dials, often featuring Breguet numerals and snailed subdials, and its impressive case and bracelet finishing. The collection is consistently described as traditional and dress-oriented, offering features like column-wheel chronographs and moon phases at competitive price points. However, some owners note drawbacks such as the subdial cutting off numerals, uninspiring pushers and crowns, and a lack of micro-adjustments on the bracelet for a perfect fit. Accuracy figures are not consistently reported across sources, with one owner noting a chronograph hour counter that doesn't always reset to zero. Overall, the Longines Master Collection is highly regarded by owners and reviewers for its sophisticated aesthetics and strong value proposition, particularly for its dress watch and chronograph models.

Yema Skin Diver CMM.20

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.
