Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Warning!
Leaving the watch in bright light to charge its rechargeable battery 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
Charging Guide
After a full charge, timekeeping remains enabled for up to about four months.
• The following table shows the amount of time the watch needs to be exposed to light
each day in order to generate enough power for normal daily operations.
• Since these are the specs, we can include all the technical details.
• Watch is not exposed to light
• Internal timekeeping
• Analog hands operational 18 hours per day, sleep state 6 hours per day
• 10 seconds of alarm operation per day
• 1 time calibration reception per day
• Stable operation is promoted by frequent charging.
Exposure Level (Brightness)

The table below shows the amount exposure that is required to take the battery from
one level to the next.
• The above exposure time values are all for reference only. Actual required exposure
times depend on lighting conditions.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Features
• If you leave the watch in the Home Position Adjustment Mode for two or three
minutes without performing any operation, it returns to the Timekeeping Mode
automatically.
• If you do not perform any operation for about two or three minutes while a setting
mode is selected, the watch will exit the setting mode automatically.
Scrolling
• The D and B button are used to change the hand setting in various setting modes.
In most cases, holding down these buttons will start high-speed movement of the
applicable hand(s) and day.
• High-speed movement of hands and day will continue until you press any button, or
until the moving hand(s) and day finishes one complete cycle.
- One complete cycle for the hands is one revolution (360 degrees) or 24 hours.
- One complete cycle for the day is 31 days.
Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal bounces off the ionosphere. Because of this, such factors
as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make manually.
• The watch is designed to update the date and day of the week automatically for the
period January 1, 2001 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±20 seconds a month at normal temperature.
Timekeeping
• The year can be set in the range of 2001 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced or when battery power drops to
Level 3.
• The date will change automatically when the current time reaches midnight. The
date change at the end of the month may take more time than normal.
• The current time for all city codes in the Timekeeping Mode is calculated in
accordance with the Greenwich Mean Time (GMT) differential of each city, based on
your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
*UTC is the world-wide scientific standard of timekeeping. It is based upon
carefully maintained atomic (cesium) clocks that keep time accurately to within
microseconds. Leap seconds are added or subtracted as necessary to keep UTC
in sync with the Earth’s rotation. The reference point for UTC is Greenwich,
England.
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 are actually two sleep state levels: “second hand sleep” and “function sleep”.
• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
• The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch
is already in the sleep state when 6:00 AM arrives, however, it will remain in the
sleep state.
Operation
Second hand only is stopped, all other functions are
enabled.
• All functions, including analog timekeeping, disabled
• Internal timekeeping maintained
Elapsed Time in Dark
60 to 70 minutes
(second hand sleep)
6 or 7 days
(function sleep)
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area.
• Press any button.
