What people say

Owners + reviewers, side by side

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

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.

Yema Superman Slim CMM.20

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.
