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 Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
