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. We use sapphire crystal for this and for the transparent back in the 358 Sa PILOT. Creating such glasses requires a high level of craftsmanship and represents a specialised skill within the field of fine watchmaking. The watches incorporate the Valjoux 7750 calibre and feature chronograph functions plus a date and day display.
