What people say

Owners + reviewers, side by side

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

Glycine Airman GMT

Owners widely praise the Glycine Airman GMT for its value and classic design, with specific appreciation for its 39mm sizing, 200m water resistance, and beefy signed crowns. Reviewers highlight its faithful re-issue nature, retaining vintage features like the plexiglass crystal and locking friction bezel with a thumbscrew crown, while some owners note its subtle blue degrade dial and red-tipped GMT hand. Accuracy from its Sellita-based automatic movement is described as acceptable, though some owners find the dual 12-hour and 24-hour scales confusing and the slim GMT hand difficult to read. On balance, enthusiasts and reviewers rate the Glycine Airman GMT highly for its vintage charm and robust build at its 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.
