Peren OnevsYema Superman Slim CMM.20

The Peren One chronograph is praised for its successful blend of minimalist and '80s retro styles, featuring a clean bi-compax dial design and thoughtful case execution. It utilizes the reliable Seiko VK64 mecha-quartz movement, offering mechanical chronograph functions. The 40.6mm steel case provides 200m water resistance and a balanced, tool-first aesthetic with mixed finishing, complemented by the absence of a date and running seconds for a tidy dial. On balance, reviewers rate the Peren One highly for its retro-modern aesthetic and the value offered by its mecha-quartz movement.

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.
