What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Sternglas Hamburg Pro Automatik

Owners widely praise the Sternglas Hamburg Pro Automatik for its Bauhaus-inspired design, German assembly, and excellent value, with many appreciating its comfortable wearability and uncluttered dial. Specific positive notes include a substantial weight that feels good on the wrist and a pleasing matte dial texture. The Miyota 8215 movement is generally considered reliable and surprisingly accurate, though some owners find it louder than expected and note the lack of hacking seconds. Caveats include a minimal instruction manual, an initially stiff strap, and a date window recess that can make the date difficult to see. Owners are split on the case finishing, with some finding it not too bad and nicely polished, while others criticize it. The case is also described by some as thick, making it potentially awkward for long-sleeved shirts. On balance, owners and reviewers rate the Sternglas Hamburg Pro Automatik highly for its attractive Bauhaus design and strong value proposition.

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.
