Sinn - 856 UTC

The technical specifications of the 856 UTC provide impressive proof of our craftsmanship in the area of instrument watches. The second time zone on a 24-hour basis makes it ideal for people who frequently find themselves crossing time zones because of travel.

The aesthetics of this watch are determined by the striking form - a form which, as in all our watches, is dictated exclusively by the functions. The 856 UTC also features a range of technologies which, together, guarantee maximum reliability even in the most extreme of conditions.

In addition, the 856 UTC has a second time zone on a 24-hour basis with a hand which helps to locate the points of the compass. The hand is designed in the form of an arrow for this very purpose. The basic principle is simple: in the northern hemisphere, you hold the watch horizontally and turn it so that the 12-hour hand is pointing towards the sun - the 24-hour hand will then be pointing North. In the southern hemisphere, on the other hand, the same procedure will cause the hand to point South.
