Quartz movement. Features two imprint areas-the dial and a motion shape. The motion within the clock lens animates the message and captures your attention to make this design an exceptional advertising medium! This unique feature is located at the botton of the clock dial and moves left and right like a pendulum. The shape of the design for the "motion-picture" can be completely custom, but must fit within a 3 1/4" square area. Standard shapes available are oval, rectangle, circle and square. Please contact customer service for custom shape die charge.
