Watch faces can use small system icons that display the status of a particular function or setting on the screen.
Unread notifications are shown with a dot at the 9 o’clock position. Only one indicator is shown regardless of the number of notifications. The dot is colored orange for regular notifications and red for urgent ones. Make sure that this indicator is clearly visible when you choose a background color for your watch face. The notification indicator will also show on the always-on and active states of your watch face.
Watch faces also display an ‘ongoing’ icon at the bottom of the screen, which allows fast access to currently running apps.
