    This exceptional clock exhibits technical achievements of the highest degree and also an extraordinarily imaginative design. The first mystery clock was created by Maurice Couet in 1913. The first example produced was sold at Cartier in New York to the American financial magnate J.P. Morgan. The fascinating "art of illusion" achieved by this timepiece has the clock hands seemingly floating in space without any connection to the movement. The hands are set on two clear revolving discs with toothed metal outer rims that are propelled by gears hidden in the outer clock frame. Cartier mystery clocks are all unique, individual artistic creations that rarely appear for public sale. The present example is especially fine with a design reflecting the earlier Art Deco inspired masterpieces.
