What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Gent Quartz

Owners widely praise the Hamilton Jazzmaster Gent Quartz for its dressier, unique aesthetic, with specific admiration for the dark, iridescent dial and the machine-work on the minute markers. The 40mm size is considered suitable for smaller wrists, though lug-to-lug measurements are debated. Some owners find the open-heart dial busy and difficult to read due to silver lines resembling hands, and the skeleton version is also noted for excessive branding. The H-20-S movement in the skeleton model is thought to have a 42-hour power reserve. Overall, owners appreciate the Hamilton Jazzmaster Gent Quartz for its distinctive mid-century modern design and detailed finishing.

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.
