Parmigiani is playing the age old cat and mouse game with this clock. The cat is trying its best to get hold of the mouse, and the presumably clever mouse is running for its life. Sadly for the cat, there is no catching this mouse. The cat moves in a one hour circuit, while the mouse continuously runs away from it. Should the cat and mouse end up in the same position, the mouse leaps away to escape the clutches of the cat.
