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.

Zelos Aurora Moonphase

Owners widely praise Zelos for offering excellent value, solid build quality, and enthusiast-friendly designs, with unique dial variants often selling out quickly. The Zelos Aurora Moonphase is noted as a desirable model, though finding one can be challenging. Some owners find Zelos's designs, including those of the Aurora line, to be too flashy for everyday wear, preferring a more subdued aesthetic. One owner reported their Zelos Aurora Nebula 38mm running at -5.3 seconds per day. Overall, owners rate the Zelos Aurora Moonphase highly for its desirable microbrand status and unique dial appeal.
