I’ve tried a AA battery but no movement, battery appears to be slightly loose. May be part connection issue so selling as not working. Could be used as display piece as Collectable or parts? Crack to centre running down front of screen only visible in certain light see second photo. some damage to casing by rim. (Photographed) This is an Alarm clock so back part pops up to set then one hand movement to silence (like in the good old days) Please see all photos as part of description
