What people say

Owners + reviewers, side by side

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

Halios Universa II

Owners widely praise the Halios Universa II for its applied indices, excellent finishing for the price, and comfortable 38mm dimensions. The integrated bracelet design with a satisfying micro-adjust clasp and case architecture are described as masterclasses. However, some find the bracelet clasp chunkier than the overall design, and the angular lug design is noted as not being for everyone. One owner reported unexpected pastel dial colors and a poor winding action. On balance, owners rate the Halios Universa II highly for its applied indices and excellent finishing at the price point.

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.
