Wall clock
 An clock has separate rotary dials and separate stationary hands for indicating separate units of time. The dials are rotated at speeds representative of different units of time, such as seconds, minutes and hours, while the hands are maintained stationary. The rotary dials are suspended vertically from one another, and the hands are kept stationary using a counter-balancing weight or the like.
