What people say

Owners + reviewers, side by side

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

Hemel HFT20

The Hemel HFT20 Chronograph is praised for its legible matte black dial, sapphire crystal, and the satisfying sweep of its chronograph hand, powered by the Seiko VK64 meca-quartz movement. Reviewers note its convenient wearability, with a 42mm case that wears well due to its 49mm lug-to-lug measurement, and a comfortable, well-made leather strap. However, its 16mm thickness is considered slightly more than ideal for the movement, and the chronograph minutes sub-dial does not precisely jump. Overall, reviewers find the Hemel HFT20 to be an accessible and modern interpretation of vintage designs, offering good value at $449.

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.
