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.

Yema Wristmaster Slim Small Seconds CMM.29

Owners widely praise the Yema Wristmaster Slim Small Seconds CMM.29 for its slim 9.5mm case, unique nature-inspired dial, and brushed steel finish. The micro-rotor movement is noted for its 4Hz beat rate and 42-hour power reserve, regulated to -/+ 10 seconds per day. Some owners report concerns regarding the movement and warranty process, while a reviewer questioned the value proposition at its price point and noted minor finishing inconsistencies on a prototype. On balance, the Yema Wristmaster Slim Small Seconds CMM.29 is highly regarded by owners for its distinctive design and comfortable wearability.
