Reviews

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

Dan Henry 1975

Owners widely praise the Dan Henry 1975 for its attractive dial, orange accents, bubble crystal, and thin, wearable 39mm case, offering excellent value. Reviewers note its retro styling and boxed sapphire crystal, while some owners highlight its fantastic lume and impressive inner rotating crystal bezel. One owner found the black sapphire bezel can wash out in certain light, and another user reported weak lume on their example. The watch utilizes an automatic movement, and accuracy figures range from -10/+30 seconds per day. Overall, owners and reviewers rate the Dan Henry 1975 highly for its retro styling and exceptional value.

From video reviewers

The vintage aesthetic and color options of the dial are a shared strength. The lume performance is a noted weakness. Reviewers disagree on whether the watch's design is ultimately a hit or a miss.

Yema Superman Slim CMM.20

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.

From video reviewers

The upgraded CMM.20 micro-rotor movement is a significant enhancement. Reviewers noted the slim profile and redesigned case. One reviewer indicated a significant flaw was discussed, but the nature of this imperfection was not specified.
