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 GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.

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.
