watch until value change

var watchVar = $scope.$watch('value', function(newValue , oldValue){
  if(newValue!=oldValue){
  //value changed remove watch
  watchVar();
 }
});

   //try this (please inject $interval service to your controller)
    var execueMe = function () {
        //your stuff
    }

    $interval(execueMe, 3000); //will trigger every 3 seconds
