Mine neither.  Maybe someone will use inductive charging or solar
power like my G-shock WWVB watch.  That one just has solar cell around
the edges since it's opaque brown.  I read somewhere of the
development of an organic solar material that is semi-transparent.
Perhaps they could coat the whole crystal with the stuff.
