Casioâ€™s Bluetooth Low Energy Watch prototype shown at CES demonstrated some of the new functionality that Bluetooth low energy will support, including:
* Incoming call and message (including e-mail) alerts on the watch;
* The ability to stop ring alerts from the watch;
* The ability to locate a misplaced phone by activating the alarm and vibration functions of a smartphone from a button-press on the watch;
* Time and date-synchronization from smartphone to watch (ensuring the watch always displays the correct date and time â€“ even across different times zones).
