These are the clocks that fuse a colorful modern art sensibility with 21st century functionality. Found in the gift shops at the Getty Museum and the San Francisco Museum of Modern Art, both clocks depict the time differently. The Spectrum model displays the time using three rotating disks with mathematical shapes that revolve continuously and silently while pointing to the hours, minutes, and seconds. The Hexagon model depicts the time using shapes on the face that align at noon, midnight, and every two hours in-between while forming a hexagon. With a stand for table display or may be hung on a wall. Wooden case lacquered in a black satin finish. Each requires one AA battery. Select Spectrum or Hexagon. 9" H x 9" W x 2" D. Sold Separately.
