Based on the classic Sinn 356 instrument chronograph, the Sinn 358 series offers a 42 mm diameter case and features a combination of clarity, functionalism and elegance.
However, it is not only the size which distinguishes these chronographs but also the conspicuous domed glass. The watches incorporate the Valjoux 7750 calibre and feature chronograph functions plus a date and day display.
