What people say

Owners + reviewers, side by side

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

Hamilton American Classic Spirit of Liberty Auto

Owners widely praise the Hamilton American Classic Spirit of Liberty Auto for its classical design, quality finishing, and refined presence, with its silver sunburst dial and rose gold accents frequently highlighted as beautiful. The H-10 movement offers an 80-hour power reserve, and some find the 42mm case size and 12mm thickness ideal for wearability. However, legibility can be an issue due to thin hands on the reflective dial, and the laser-engraved quote on the strap is a common point of contention, with some finding it detracts from the strap's appearance. Concerns are also raised about its limited versatility for everyday wear due to its dressier style, low water resistance, and lack of crown guards. Overall, owners and reviewers rate the Hamilton American Classic Spirit of Liberty Auto highly for its attractive design and value for money, particularly its movement and finishing.

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.
