What people say

Owners + reviewers, side by side

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

Baltic Hermétique Summer

Reviewers highlight the Baltic Hermétique Summer's compact 37mm brushed case with a polished bezel and 150 meters of water resistance. The watch features glossy dials in bright colors with raised BGW9 Super-LumiNova indices that emit a strong blue glow, and it comes with color-matched FKM rubber straps or Baltic bracelets. The Miyota 9039 movement supports hacking and hand-winding. However, the recessed crown can be difficult to manipulate if fingernails are not long enough, and the movement has a stated accuracy of -10/+30 seconds per day. Overall, reviewers praise the Baltic Hermétique Summer for its well-balanced, colorful dials and strong lume at an affordable price point.

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.
