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 Comet 39

Owners widely praise the Zelos Comet 39 for its wearable 39mm size, thin profile under 10mm thanks to its manual-wind Sellita SW215 movement, and its captivating dial with a deep starburst effect. The winding action is described as a joy, and the watch is considered a stunner for its price, blending modern and vintage aesthetics. Some owners note frustration with Zelos's limited production runs leading to quick sell-outs. One owner found the logo childlike, while another experienced strap-rubbing issues with the short lugs, which were resolved with a Milanese bracelet. Overall, owners and reviewers rate the Zelos Comet 39 highly for its excellent value and striking dial design.
