What people say

Owners + reviewers, side by side

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

Sternglas Naos Pro Automatik

The Sternglas Naos Pro Automatik is praised for its slim 9mm case and Bauhaus dial design, featuring clear hour markers and a framed date window. Owners note the upgraded Miyota 9015 movement with a 4Hz beat rate. Accuracy is reported as -10/+30 seconds per day, which is not ideal for precision enthusiasts. The five-link bracelet's lack of fitted end-links and the optional bracelet's chunkiness are flagged as areas lacking refinement. Overall, reviewers highlight the Sternglas Naos Pro Automatik's improved wearability and premium feel at its price point.

From video reviewers

The Bauhaus design is a strength. The value proposition is a weakness.

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.
