What people say

Owners + reviewers, side by side

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

Sugess MoonPhase Master S394

Owners widely praise the Sugess MoonPhase Master S394 for its impressive value, offering multiple complications at a sub-$200 price point, with one owner highlighting its deep blue dial and applied markers. While one owner finds the 14mm thickness acceptable and wearable, another notes the included straps are subpar and the movement finishing is rough under magnification. The long lugs can also create a noticeable gap with the strap. On balance, owners rate the Sugess MoonPhase Master S394 highly for the significant complications and aesthetic appeal it delivers at its accessible price.

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.
