The most striking feature of the Sinn U1 SDR is the white bar hands, whose length is perfectly matched to the indices. The hour, minute and second hands are luminescent, creating a harmonious contrast with the black dial. Optimum readability guaranteed. The 44 millimetre case diameter also ensures a perfect view of the time.

The Bazel is also extremely resistant to scratches and rust, thanks to the Tegiment technology of the watch.
