What people say

Owners + reviewers, side by side

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

CWC 1983 RN Divers Quartz Re-Issue Watch

Owners widely praise the CWC 1983 RN Divers Quartz Re-Issue Watch for its historically accurate reproduction, thin profile for a 300m diver, and a second hand that aligns well with indices. Reviewers note its reasonable size on smaller wrists, original dial layout with markers touching the chapter ring, and a broader minute hand. However, criticism is directed at the fixed 20mm bars necessitating specific strap types and the mismatched lume colors between hands and hour markers, with some finding the convex lume on the markers overly shiny. Overall, owners rate the CWC 1983 RN Divers Quartz Re-Issue Watch highly for its accurate vintage aesthetic and wearability.

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.
