About This Manual
Things to check before using the watch
1. Hold down C for about two seconds to enter the Timekeeping Mode, and
then observe the movement of the x Second Hand.
Is the x Second Hand moving smoothly at one-second intervals?
Is the x Second Hand moving at
two-second intervals or is it stopped
completely?
Power is low. Charge the watch by placing
it in a location where it is exposed to light.
For details, see "Charging the Watch".
2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under "To configure Home City settings" to configure your Home
City and daylight saving time settings.
Important!
World Time settings depend on correct Home City, time, and date settings in the
Timekeeping Mode. Make sure these settings are configured correctly.
3. Set the current time.
See "Configuring Current Time and Date Settings".
The watch is now ready for use.

Charging the Watch

The face of the watch is a solar cell 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.
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
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.

Go to step 2.
When wearing the watch,
makes sure that its face is
not blocked from light by the
sleeve of your clothing.
• The watch may enter a
sleep state if its face is
blocked by your sleeve
even only partially.
Power Levels
You can get an idea of the watch's power level by
observing the movement of the x Second Hand in the
Timekeeping Mode.
• If the x Second Hand is moving normally at one-second
intervals, power is at Level 1.
• If the x Second Hand is moving 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.
Moving at two-second
intervals.
Level Hand Movement
1 Normal.
x Second Hand moving at two-second
2 intervals.
m Day changes to 1 (home position).
x Second Hand stopped.
3 z Hour Hand and c Minute Hand stopped
at 12 o'clock.
• 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
sufficiently during this period, the analog 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 stops hand operation
temporarily whenever power suddenly drops below a certain level due to overuse
of the alarm tone over a short period. Note that all operations are disabled while the
watch is 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 above exposure times all are for reference only. Actual exposure times depend
on lighting conditions.
• For details about the operating time and daily operating conditions, see the "Power

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 x Second Hand only is stopped at 12 o'clock, all other
sleep) functions are enabled.
• All functions, including analog timekeeping, disabled
6 or 7 days (function sleep)
• Internal timekeeping maintained.
• 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 or press any button.
