Definition: The unwatch method is available to all Javascript objects. It is used to remove a watch point to a property of that object that was previously added using the watch method. A watchpoint monitors the property and can manipulate the value of the property if required. This is not a reserved word so you can declare your own variable or function called unwatch but if you do then you will not be able to use the method.
Examples:
myfield.unwatch(property1);
