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.

Tudor Pelagos Ultra

The Tudor Pelagos Ultra is praised for its 1000 meters of water resistance, METAS-certified Calibre MT5612-U movement, and fully lumed dial and bezel. Reviewers highlight its titanium case and self-adjusting clasp as key features. The Tudor Pelagos Ultra is slightly larger at 43mm than some other models in the line but wears comfortably. Overall, owners and reviewers rate the Tudor Pelagos Ultra highly for its technical specifications and comfortable wearability as a flagship dive watch.

From video reviewers

The Tudor Pelagos Ultra's all-titanium construction provides a lightweight and durable case. One weakness is the lack of lume brightness. Reviewers disagree on whether the helium release valve is a notable feature or a drawback for a more streamlined design.
