Utilizing advanced LED technology (not to be confused with a simple color wheel), you'll be amazed with the variety of colors that are achieved as time goes by. Watch and listen as the DreamTime clock announces the time with a gentle chime and flashes of light on every hour and half an hour. Activated by your touch, the DreamTime clock chimes the exact time to the minute! Requires 3 AAA batteries, not included. Size: 6"x6"x6".
