The clock resembles one of Dali's melting timepieces, & is perfectly balanced to hang off your desk or shelf. Weird as it looks, the Dali Clock keeps excellent time thanks to its precision movement & persistent memory. Requires 1x AA battery (not included), Measures Approx. 19 (h) x 15 (d) x 12 (w) cm, Perfectly balanced & rests off the edge of any flat surface, We've always been fascinated by Dali's melting clocks. An art historian once explained them as "a Surrealist meditation on the collapse of our notions of a fixed cosmic order.", We may no longer be sure of cosmic order, but we do know how much we love this Dali Clock.
