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 HYDROCONQUEST

Owners widely praise the Longines Hydroconquest for its attractive sunburst blue dial and accurate timekeeping, with one owner reporting a loss of only 2 seconds per day. However, the bracelet is frequently criticized for lacking micro-adjustments and having pinch-prone links, and the screw-down crown is noted as inconvenient and difficult to operate by multiple owners. Some owners also flag the bezel action as ratchety with back play, and one owner found the lugs sharp and the overall design uncomfortable, leading them to sell the watch. On balance, owners appreciate the Longines Hydroconquest's aesthetic appeal and value, despite significant reservations about its bracelet and crown usability.

From video reviewers

The bezel action is praised for its smooth and precise rotation. Lume brightness is a shared weakness, found to be somewhat lacking. Reviewers disagreed on the watch's value proposition compared to alternatives.
