(Disclaimer: I am not an Apple fan.)
As for the design itself, there is the blatant copying of the seconds hand, but otherwise it seems whoever did it took some care to differentiate the apple clock from the original. E.g. how the lengths of the hour and minute hands relate to the radius of the clock and the size of the hour and minute tick marks. Then of course there are obvious implications of being viewed on a tiny 4" screen. Whether that is enough to build a legal defense on, I have no idea.
