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 GMT

Owners widely praise the Longines HYDROCONQUEST GMT for its excellent finishing, smooth winding action, and overall value, with some finding its build quality and colorways superior to higher-priced competitors. Reviewers and owners alike note its robustness as a traveler's dive watch with a true GMT movement. Some owners find the round markers at 6 and 9 disrupt dial symmetry, and the GMT hour markers are described as tiny and difficult to read. The date wheel can be mismatched on certain dial colors, and the bracelet clasp is noted as sharp by one reviewer. While some owners wish for a smaller case size, others find the 41mm comfortable. The bezel action is flagged as having bounce-back by one owner, though the brushed finish effectively hides wear. Overall, owners and reviewers rate the Longines HYDROCONQUEST GMT highly for its robust build and excellent value proposition.
