Although a great idea and a lot of money, the decision to change to frequency really hurt the sales of these watches. I got rid of mine, just in time! If you are lost at sea or "known-to-be" lost elsewhere, the frequency will be monitored...??? Other than that, no dice! I would love to know the thinking behind such a change. I guarantee Breitling had nothing to do with it.
