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.

Tissot PRX Titanium

The Tissot PRX Titanium is widely praised for its lightweight titanium construction, impressive machining, and the 38mm size hitting a sweet spot for wearability. Owners and reviewers highlight the Powermatic 80 movement's 80-hour power reserve and anti-magnetic Nivachron balance spring. Some find the colorways and materials less appealing than standard steel options, with legibility noted as a potential issue, and one reviewer expressed a preference for different hand and marker tones against the anthracite dial. Owners discuss the Powermatic 80 movement's use of plastic parts, with some concerned about serviceability while others note Tissot offers movement replacement. On balance, owners and reviewers rate the Tissot PRX Titanium highly for its comfortable wearability and robust movement at its price point.
