Most timepieces have hands that turn clockwise, and the reason is much older than clocks themselves.
The first thing most of us notice about clocks and watches when we learn to tell time, is that the hands turn clockwise – the habit of perceiving clockwise motion as a representation of the forward movement of time is deeply ingrained; so much so that once having learned it, most of us cease to notice it at all. Imagine you are standing on the center of a watch: in any direction you face, the hands will appear to pass from left to right. Theoretically, we could just as easily tell time if they went from right to left, so why do clock and watch hands overwhelmingly have rightward, or clockwise, motion? Why is there no period in history where anticlockwise and clockwise rotation competed for supremecy.
