4 ?? across the face, 7? high from top of bell bar to bottom of feet and 2 ?? wide (thick). Runs on batteries. An awesome looking alarm clock with that, literal, Old School look. Not a wind up but a battery operated clock. One of the coolest old school items to have, next to a rotary phone. The Superman twin bell alarm clock is a cool blast from the past with a classic image of Superman This alarm clock lights up too!
