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.

Tissot PRC 100 Solar

Owners and reviewers highlight the Tissot PRC 100 Solar's value and modern, urban aesthetic, with its slim 9.2mm case and good finishing for the price. The solar movement is a key feature, offering a 14-month power reserve and rapid charging capabilities. Some owners find the dial colors a bit uninspired, and the date window placement is disliked, while the second hand's ticking is noted as a drawback compared to automatic movements. The watch's 39mm case is considered versatile, though some prefer a smaller 35-37mm size. Overall, owners and reviewers consider the Tissot PRC 100 Solar a versatile daily wear, particularly for its solar technology and Swiss-made appeal at its price point.
