Scurfa Diver One D1-500 NDvsYema Superman Slim CMM.20

The Scurfa Diver One D1-500 ND is widely praised for its 40mm case size, which owners find comfortable for everyday wear and reminiscent of classic dive watch proportions. Reviewers highlight its robust build, precise bezel, and excellent anti-reflective sapphire crystal, contributing to high legibility alongside its handset. The aluminum bezel offers a distinct aesthetic, and the 500-meter water resistance is considered more than adequate for recreational diving. One owner noted the lume is good, though not as strong as on other Scurfa models. Overall, owners and reviewers rate the Scurfa Diver One D1-500 ND highly for its comfortable wearability and tool-like legibility at its price point.

Owners widely praise the Yema Superman Slim CMM.20's appealing retro design, 39mm case, and the in-house CMM.20 micro-rotor movement, with some specifically noting the fish scale bracelet. Reviewers and owners alike mention the movement's design can lead to a "jittery" seconds hand, though Yema states this does not impact performance. Some owners question the $2500 MSRP, finding it overpriced, while others note initial stiffness in the bracelet that improves with wear. Finishing inconsistencies were noted on a prototype, and the stamped clasp on the bracelet is considered subpar by one reviewer. Overall, owners and reviewers find the Yema Superman Slim CMM.20 a compelling option for its vintage styling and unique micro-rotor movement, despite some concerns about its value proposition and minor execution details.
