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.

Tissot PRC 100 Solar

Owners and reviewers highlight the Tissot PRC 100 Solar's value and modern, urban aesthetic, with its slim 9.2mm case and good finishing for the price. The solar movement is a key feature, offering a 14-month power reserve and rapid charging capabilities. Some owners find the dial colors a bit uninspired, and the date window placement is disliked, while the second hand's ticking is noted as a drawback compared to automatic movements. The watch's 39mm case is considered versatile, though some prefer a smaller 35-37mm size. Overall, owners and reviewers consider the Tissot PRC 100 Solar a versatile daily wear, particularly for its solar technology and Swiss-made appeal at its price point.
