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.

Peren One

The Peren One chronograph is praised for its blend of minimalist and retro styling, featuring a clean bi-compax dial with applied indices and diamond-cut hands. Reviewers note its detailed dial execution, thoughtful case and bracelet finishing, and the use of applied Globolight markers with BGW9 Super-LumiNova. The watch utilizes a Seiko VK64 mecha-quartz movement, offering quartz accuracy with a mechanical chronograph feel, and boasts a 200-meter water resistance rating within its 40.6mm steel case. Overall, reviewers highlight the Peren One's strong value proposition driven by its design and finishing.
