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.

Redux Zero-Hour

Owners widely praise the Redux Courg Type 39MM for its robust, no-nonsense design and good overall quality, with a reliable Seiko NH53A movement keeping time well. The titanium case and crystal have shown scratch resistance, and the bezel action is described as tight by some. Reviewers note the proprietary RDXB1 or blue lume glows brilliantly, though briefly. Some owners flag the crown stem as flimsy and the unidirectional bezel as having some play. Overall, owners rate the Redux Courg Type 39MM highly for its functional tool-watch design and durable titanium construction.
