Why would you want to keep a reference to a changewatcher and call unwatch()?..

Answer / Varun Yadav

You might want to keep a reference to a ChangeWatcher and call unwatch() in Adobe Flex when you no longer need to listen for property changes on an object. This is important to prevent memory leaks by avoiding unused listeners.
