What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt 12-hr

Oak & Oscar The Humboldt 12-hr owners widely praise its comfortable, solid bracelet with screw links and tight end-link fit, along with its awesome sandwich dial featuring superb grain and crisp details. The 12-hour bezel is noted as excellent for tracking a second time zone, and the orange second hand adds a nice pop. One owner reports the watch has outstanding quality and a perfect fit on smaller wrists, while another notes its legibility and great presence on various straps. A reviewer describes it as a 40mm stainless steel tool watch with a matte, brushed finish and a sandwich dial, powered by an ETA 2892-A2 movement with a 42-hour power reserve. Some in the line report the lume could be brighter. On balance, owners and reviewers rate Oak & Oscar The Humboldt 12-hr highly for its build quality and versatile tool-watch design.

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.
