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 Flygraf CPA10

Owners widely praise the Yema Flygraf CPA10 for its light 40mm titanium case, slim 9.4mm profile, and excellent legibility on its blue brushed dial with applied Super-LumiNova markers. The Yema CMM.10 automatic movement is considered terrific, offering chronometric precision of -3/+5 seconds per day and a 70-hour power reserve. Some owners appreciate the aluminum warranty card and packaging as nice touches. The watch is priced at €1,690. One owner noted concerns about the long-term reliability of older in-house movements due to mixed origins, though praised customer service under new management. Overall, owners rate the Yema Flygraf CPA10 highly for its comfortable wearability and attractive, legible dial design.
