Sinn 256 Ty

Sinn 256, Sinn 256 Ty are chronographs by Sinn.

Sinn calls this series "Universal Chronographs". The peculiarity of the models with the proven automatic chronograph movement Valjoux 7750 lies in the slightly smaller case (38.5 mm diameter), which for many wrists turns out to be the appropriate size.
