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 Date

Owners widely praise the exceptional build quality for the price, noting a solid feel, quiet rotor, and good bezel action on the Tornek-Rayville TR-660 Acrylic Date. Reviewers highlight its utilitarian, non-reflective matte black dial and the inclusion of a moisture detector, echoing its military-issued predecessor. One owner found the lume dim and short-lived. Overall, owners rate the Tornek-Rayville TR-660 Acrylic Date highly for its robust construction and military-inspired design cues at its price point.

Yema Skin Diver Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.
