Longines MASTER COLLECTIONvsYema Superman Slim CMM.20

Owners widely praise the Longines Master Collection for its excellent value, classic styling, and impressive finishing, with specific call-outs for its beautiful dials, Breguet numerals, and the smooth winding feel of its movements. Reviewers and owners alike highlight the value proposition, particularly for complications like annual calendars and chronographs, often citing the L893 caliber's 72-hour power reserve. Some owners find the collection's traditional design less appealing than sportier alternatives, and a few note minor drawbacks such as a subdial obscuring a numeral or a bracelet lacking micro-adjustments. One owner reported a potential issue with the moon phase setting mechanism. Overall, the consensus is that the Longines Master Collection offers significant value and refined styling, making it a highly regarded choice for a Swiss dress watch.

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.
