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.

Sinn 903 St II

The Sinn 903 St II is widely praised for its robust build quality, over-engineered feel, and strong value proposition, featuring 200 meters of water resistance and a La Joux-Perret L110 column-wheel chronograph movement. Owners appreciate the hybrid ceramic lume and the practical functionality of the slide rule operated by the bezel. However, reviewers note that the busy slide-rule dial can make time-reading challenging, with some finding the chronograph hand's placement over the "12" numeral less refined. On balance, owners and reviewers rate the Sinn 903 St II highly for its exceptional build quality and value, particularly its robust water resistance and functional slide rule at its price point.
