Reviews

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

Revelot Hexmariner 39 Mahjong Bicolor Limited Edition

The Revelot Hexmariner 39 Mahjong Bicolor Limited Edition's design is widely loved, though owners note it sells out instantly, making it difficult to acquire. Some owners question the consistency of the gold tone between the 39mm and 42mm bicolor models, with the 39mm appearing more yellow gold. A reviewer flagged issues with the bracelet, specifically misaligned and poorly made solid end links with sharp inner links, and inconsistent brushing on the case. On balance, owners appreciate the design of the Revelot Hexmariner 39 Mahjong Bicolor Limited Edition, but the difficulty in obtaining it and reported bracelet quality issues temper enthusiasm.

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.
