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.

Gruppo Gamma Field III GMT Date

Owners widely praise the Gruppo Gamma Field III GMT Date for its awesome looks, quality, and good value. The watch features a 40mm brushed 316L stainless steel case, box sapphire crystal, and 200m water resistance, powered by a Seiko NH34A movement. Some reviewers note the NH34A movement's accuracy can range from -20~+40 seconds per day, though one reviewer reported +5 seconds per day with a regulated movement. The dial's dense layout with Arabic numerals can be overwhelming for some, and one owner found the size unsuitable for smaller wrists. On balance, owners rate the Gruppo Gamma Field III GMT Date highly for its impressive finishing and toolish design at its price point.
