The watch obviously does not behave exactly like a human, so there is
no reason why it should understand time in the same way as a human
does. The point is that is impossible to make a brain or brain
component that behaves *exactly* like the natural equivalent but lacks
understanding. Note that this says nothing about programs or
computers: it is impossible through *any means whatsoever* to make
such a device, even even if you could invoke magic.
