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.

Formex Stratos UTC

Owners and reviewers widely praise the Formex Stratos UTC for its user-friendly flyer GMT complication, which utilizes pushers for time-zone adjustments, and its slim 11.8mm case. The watch is noted for its intricate, hand-finished case with a multi-layer construction and excellent finishing, along with a unique two-level case design. The Dubois-Depraz module on an ETA 2892 movement is a highlight, with accuracy figures ranging from +/- 5 to +/- 7 seconds per day. However, some find the dial busy with multiple typefaces and the overall design too complex or "plug ugly," with the price near €4000 considered high by some for a newer brand. Overall, owners and reviewers rate the Formex Stratos UTC highly for its innovative GMT functionality and excellent case finishing at its price point.
