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 Acrylic Non-date

The Tornek-Rayville TR-660 Acrylic Non-date is a 40mm bead-blasted stainless steel watch with a utilitarian matte black dial and a moisture detector, measuring 14.7mm thick and 48.5mm lug-to-lug, featuring a subtly domed, AR-coated crystal. One owner notes a preference for a different watch's bezel-locking mechanism but appreciates the TR-660's 20mm lug size. Another owner reports damage to the case and bezel, though it includes unused and worn straps. On balance, owners find the Tornek-Rayville TR-660 Acrylic Non-date to have a timeless design that remains appealing.

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.
