Power Saving

Power Saving

When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.


  • For information about enabling and disabling power saving, see “To turn Power Saving on or off” (page E-93).
  • There actually are two sleep state levels: “display sleep” and “function sleep”.
  • The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.
  • Power Saving is enabled only when the watch is in the Timekeeping Mode with the Day of the Week screen displayed (page E-29) or in the World Time Mode (page E-75).

To recover from the sleep state
Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page E-89).
