When a phone comes in on the smartphone, the watch displays a notification and vibrates. If the caller’s number is registered in contacts, the watch will display the caller’s name and image (when one is available).
To accept the incoming call, swipe the touch screen from right to left. You will then be able to talk with the caller on the smartphone.
To reject an incoming call, swipe the touch screen from left to right.
You can also respond with a message using one of the preset responses.
