I just realized that the standard time watch face feels like it will follow the sun rising from left to set on the right side. But since the sun is rising in the east, it should be horizontally reversed. Or you should always look to the south / to the sun. Or it feels right because of my western idea of writing from left to right?
A 24 hour clock with midnight at the bottom tracks the motion of the sun if you are in the Northern Hemisphere looking South. If you are in the Southern Hemisphere looking North you need a clock that goes anti-clockwise.
