Defective E. Howard & Co. radio-controlled watch

Ok place watch on window ledge inside house ..when you go to bed make sure its sat on a book with nothing else in its way except the glass window, the signal should be picked up by your watch between midnite and 3am that is sent from one of 5 world wide beacons.if this does not work have battery refitted and make sure the repairer AC's the watch this has to be done any repairer will know what you mean..
