What people say

Owners + reviewers, side by side

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

Tornek-Rayville TR-660 Sapphire Non-date

Owners widely praise the Tornek-Rayville TR-660 for its quality, good timekeeping, and suitability as a military diver reissue. The 40mm bead-blasted 316L stainless steel case, sapphire bezel inlay, and Arclite Super LumiNova are noted features, powered by a Japanese TMI NH38 automatic movement and water-resistant to 20 ATMs. Some owners suggest alternatives due to availability issues with the small-batch releases. Overall, owners rate the Tornek-Rayville TR-660 highly for its faithful reissue design and quality build at its price point.

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.
