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.

Longines SPIRIT PILOT FLYBACK

The Longines Spirit Pilot Flyback is widely praised for its refined 39.5mm case size, improved wearability, and clean dial design, incorporating enthusiast feedback by removing the five stars and date. Reviewers and owners consistently highlight its exceptional finishing, well-acting ceramic bezel, and the value it offers. The manual-winding L792.4 column-wheel chronograph movement is COSC-certified and offers a power reserve of approximately 68 to 72 hours. Some owners expressed disappointment with the removal of the five stars from the dial, and one reviewer noted that some numerals are partially cut off by the subdials. The watch is priced around $5,350 to $5,550 USD. Overall, owners and reviewers rate the Longines Spirit Pilot Flyback highly for its improved dimensions, finishing, and value proposition.
