Some suggest that the 12 hands on DD's watch are 12 people over whom
he is watching, but I think that watch is strictly astrological In my
theory, the 12 hands divide the 12 houses. (In the physical world, the
sky turns and the Houses stay in place except for like 1 degree a day,
but the watch face stays in place and the House Hands turn.) The
planets around the edge move in accordance with the planets in the
real sky. DD knows, or there is some marking not specified in JKR's
description, where the constellations are. Such a watch can tell time
AND tell you the moment's astrological influences. I don't think JKR
believes in astrology, but the centaurs do.

I have no theory for Ron's watch yet.
