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 Hammerhead V3 300m Bronze

Owners widely praise the Zelos Hammerhead V3 300m Bronze for its distinctive 70s-inspired design, slim 13.5mm case, and improved lume, offering a sophisticated timepiece at an accessible price point starting at $349. The unique dial is noted for evoking an otherworldly feeling, and the comfortable bracelet features on-the-fly micro-adjustment. Some enthusiasts express frustration with shipping delays and a desire to see the watch on a wrist before purchase. One owner flags that the clasp material could be more scratch-resistant, and resizing bracelet pins can be stubborn. On balance, owners rate the Zelos Hammerhead V3 300m Bronze highly for its unique design and build quality at its price point.
