The cool new Kikkerland Big Wheel is a unique modern take on an old-fashioned analog clock. Instead of trying to read the hour and minute hands, this giant 2 foot diameter mechanical wall clock simply points to the time printed in big, bold numerals on a large constantly revolving industrial gear. The huge time sprocket makes a full revolution twice a day using four fixed internal spur gears to turn it. Although it looks like it's constructed of heavy metal, it's actually made from lightweight ABS plastic with a metallic finish, so it can easily hang from the wall without pulling it down. It's like functional artwork.
