ABSTRACT:
A clock is provided with a pendulum suspended generally upwardly from the face of the clock and an electromagnet means is provided adjacent to the periphery of the face to catch and hold the pendulum bob momentarily to indicate at least one aspect of the time such as the minutes past the hour. Preferably the electromagnet is carried on a rotating support progressively around the peripheral portion of the clock face to alter the time indication. A lighted hand may be used to indicate the time in hours. In some embodiments the pendulum may swing outwardly beyond the face of the clock.
