Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, be sure to leave it in a
location where it is exposed to light.
• Best charging performance is
achieved by exposing the watch to
light that is as strong as possible.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
• The watch may enter a sleep state
(page E-15) if its face is blocked
by your sleeve even only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot. Take care when
handling the watch to avoid burn injury. The watch can become particularly hot when exposed to
the following conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
E-12
Important!
• Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
• Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to
bright light whenever possible.
Power Levels
You can get an idea of the watch’s power level by observing the
movement of the
c
c
Second Hand
in the Timekeeping Mode.
• If the
c
c
Second Hand
is moving smoothly at one-second intervals,
power is at Level 1.
• If the
c
c
Second Hand
is jumping at two-second intervals, power is at
Level 2, which is quite low. Expose the watch to light as soon as
possible so it can charge (Low battery alert).

All functions disabled
• When power drops to Level 3, all functions will be disabled but the watch will continue to keep time
internally for about one week. If you recharge the battery suffi ciently during this period, the hands will
move automatically to the correct setting and regular timekeeping will resume. After one week, all
settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their
initial factory defaults.
Power Recovery Mode
The watch is designed to go into a power recovery mode that temporarily disables functions whenever
power suddenly drops below a certain level due to overuse of sensors, illumination, and/or the alarm tone
over a short period. All watch operations are disabled in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal operation after power
recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power
to recover sooner.

the Specifi cations (page E-83).

Power Saving
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.
• There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep)
•
c

• All other functions enabled.
6 or 7 days (function sleep)
• All functions, including timekeeping, disabled.
• All hands stopped at 12 o’clock.
• Only the
b
b
Day Indicator
operates normally.
• 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.
• The watch will not enter a sleep state while it is in the Stopwatch Mode.
To recover from the sleep state
Move the watch to a well-lit area, perform any button operation, perform a crown operation (pull-out,
rotate), or move your hand to an angle that causes an Auto Light operation.
