What people say

Owners + reviewers, side by side

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

Citizen Atomic Perpetual A-T

Owners widely praise the Citizen Atomic Perpetual A-T for its handsome appearance, solid fit and finish, comfortable bracelet, and intuitive world time function. Its perpetual calendar and atomic timekeeping are highlighted as major conveniences, maintaining accuracy within 0.5 seconds even without syncing, and owners appreciate its "set & forget" nature and solar charging. The watch features a modest, stylish blue dial with delicate design details and a clutter-free layout, along with high water resistance without a screw-down crown and light titanium construction. Some find the dial unnecessarily busy, and its time zone functionality is noted as less useful outside the US, with atomic sync being less compelling below the equator. Accuracy is reported as +/-15 seconds per month if not syncing, but +/-0 seconds if it syncs via radio signal. Some find the watch a bit on the large side.

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.
