What people say

Owners + reviewers, side by side

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

Sinn 103 St Ty Hd

The Sinn 103 St Ty Hd is widely praised as a stunning, heritage-inspired pilot's chronograph with a utilitarian feel and bold red accents on a black dial. Owners note it offers a different experience compared to typical Sinn watches. It features a hand-wound Sellita SW510 M movement, a 58-hour power reserve, 20 ATM water resistance, and impact-resistant acrylic glass. The Sinn 103 St Ty Hd is priced at €2,590 and is limited to 1,000 units. On balance, owners and reviewers rate the Sinn 103 St Ty Hd highly for its unique aesthetic and tool watch attributes.

From video reviewers

The watch's robustness and ability to withstand extreme conditions without compromising accuracy are notable strengths. The relatively high price point is a shared weakness. Reviewers disagree on the watch's thickness, with one reviewer considering it a drawback and the other not mentioning it.

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.
