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.

Spinnaker Fleuss GMT

Owners widely praise the Spinnaker Fleuss GMT for its aesthetic appeal, comfortable and light wearability, and value, especially when discounted. The textured blue dial, applied lumed markers, and sapphire crystal with AR coating are highlighted as stunning features. Owners also note the dial is very well lumed and the bracelet has helpful quick-release tabs. However, the 43.3mm case size is criticized by some as being too large, and the Beads of Rice bracelet is described as "jingly jangly" with a pressed clasp and a clasp that isn't finely finished. Some users flag the internal bezel rotates too easily. Overall, owners rate the Spinnaker Fleuss GMT highly for its aesthetic success and value at its affordable price point.
