Your watch has a dual-layer color and monochrome LCD. Switching between monochrome and color LCD screens can be performed manually, but it is also performed automatically in certain cases. The following section explains when the watch displays the monochrome LCD screen.

After entering the Timepiece Mode

The watch will use the monochrome LCD screen to display the current time after you enter the Timepiece Mode by running the Timepiece app (see “Using the Timepiece App”).

Display	Operations
	The operations described below can be performed in the Timepiece Mode. Pressing (and immediately releasing) the power button: Turns on the backlight. Holding down the power button: Exits the Timepiece Mode and starts up Android Wear. The watch does not perform any notification operations while in the Timepiece Mode.

While the “2 Layers” watch face is selected

While the “2 Layers” watch face is selected (see “CASIO Watch Faces”), the monochrome LCD screen will display the current time after the watch is left idle for some time.

Display	Operations
	Tapping the touch screen while the monochrome LCD screen is shown will switch to the color LCD screen. The display will not switch to the monochrome LCD screen if a notification card is displayed on the color LCD screen. If a notification comes in while the monochrome LCD screen is displayed, the watch will automatically switch to the color LCD screen and display a notification card.

While the watch is in the Theater mode

While the watch is in the Theater mode (see “Temporarily Blocking All Notifications and Disabling the Backlight (Theater mode)”), the watch uses the monochrome LCD screen to display the current time.

	The watch does not perform any notification operations while it is in the Theater mode. Also note that tapping the touch screen will not switch to the color LCD screen. To exit the Theater mode, press the watch’s power button.

While “Always-on screen” is OFF

While OFF is selected for the “Always-on screen” setting on the Settings screen (see “Using the Settings”), the watch uses the monochrome LCD screen to display the current time after the watch is left idle under the conditions below.

• While any watch face type is displayed

• While the Activity app or any other app that dims the display automatically after a fixed amount of time is running

Even if a notification card is displayed on the color LCD screen, the display will switch to the monochrome LCD screen (which does not show the notification card). If a notification comes in while the monochrome LCD screen is displayed, the watch will perform a vibration alert but the monochrome LCD screen (which does not show a notification card) will remain displayed.

When the charge level drops below 5%

The watch will switch to current time display using the monochrome LCD screen whenever its charge level drops below 5%, regardless of the currently selected watch face type and display settings.

While Android Wear operation is stopped due to a low charge level

The watch displays the current time using the monochrome LCD screen for a while after Android Wear operation is stopped due to a low charge level.

Display	Operations
	Though this screen has the same appearance as the Timepiece Mode screen (see “Using the Timepiece App”), the power button is completely disabled in this case. The watch does not perform any notification operations. Charging the watch will cause Android Wear to resume operation automatically after the charge reaches a certain level.
