With its technical equipment, the 856 UTC is impressive evidence of our skills in the field of instrumental clocks. Due to its second time zone on a 24-hour basis, it is particularly interesting for people who frequently have to cross time zones on their travels. The 856 UTC also has a second time zone on a 24-hour basis with an orientation pointer that makes it easier to determine the cardinal points. For this purpose, this pointer is shaped as a directional arrow. In principle, the procedure is simple: if you are in the northern hemisphere, align the clock horizontally and turn it so that the 12-hour hand points to the sun – the 24-hour hand then points north . On the other hand, if you are in the southern hemisphere, it points to the south using the same procedure.
