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.

Phoibos Voyager GMT

Owners widely praise the Phoibos Voyager GMT for its exceptional fit and finish, attractive dials that play with light, and outstanding lume. The bezel action is described as perfect with a grippy, smooth-threaded crown, and the bracelet clasp is noted as high quality for the price. Accuracy varies, with one owner reporting +1/+2 seconds per day and another around -6 seconds per day. Some owners find the 14.5mm thickness chunky and difficult to wear with long sleeves, and the 24-click bezel limits tracking to hour-offset time zones. The date color can blend into the dial, and the date wheel may show slight misalignment. On balance, owners rate the Phoibos Voyager GMT highly for its vibrant dials and excellent value.
