This clock resembles a turbine of an aeroplane. The outer rim and the central disc fixes the 60 blades where each blade is twisted along its length: at the outer rim blades are parallel to the dial surface, while in the middle they turn to be perpendicular - this gives an exciting shading effect, the wall behind the clock peeps out between blades around the central disk. On the outer rim, blades are fixed with short steel pins, these are visible like stylish screws along the perimeter.
