Mickey Mouse Alarm Table Clock Tested Bit of glue on the back. Battery terminals look clean and the clock and alarm most definitely work. Battery cover is a little loose but does stay closed. Silver hand sets when the alarm goes off which is set by turning the black gear on the back. Turn the alarm on by pulling up the button on the top. When the alarm sounds, turn it off by pushing the big button back down again. Pulling out the black gear allows you to set the time correctly (moving back or forward an hour for example). Have tested this by putting a battery into it and it ticks along nicely and still makes a good alarm sound.
