Crown Operation
–Models Equipped with a Crown Cover–
<Opening and Closing the Crown Cover>
Insert your fingernail between the case and crown cover and open
the crown cover so that it opens to the outside.
* Always make sure to close the crown cover after operating the
crown.
<Important Point when Turning the Crown for Setting
Time and Date, Correcting Time Difference or Setting
Reference Position>
Although the crown can be operated by turn-
ing while pinching between your fingers or fin-
gernails (Fig. 1), the crown can be turned more
easily by turning while pressing against the
crown with the thick portion of your finger
(Fig. 2).
* Please refer to the manual for information
on the procedures for setting the time and
date, correcting time difference and setting
the reference position.

This watch is a solar-powered watch. Make sure to charge the watch prior to
use by adequately exposing it to light. If the watch should happen to stop as
a result of being insufficiently charged, charge by exposing the watch to in-
tense light such as direct sunlight.
2. Before Using
A secondary battery is used in this watch to store electrical energy. This secondary
battery is a clean energy battery that does not contain mercury or other toxic sub-
stances. Once fully charged, the watch circuit will continue to keep time for about
2 years without additional charging (when the power save function is operating).
<Proper Use of this Watch>
To use this watch comfortably, make sure to recharge it before it stops running
completely. There is no risk of overcharging no matter how much the watch is
charged (Overcharging Prevention Function). It is recommended that the watch
be recharged everyday.
This watch is a solar-powered watch that contains a solar cell in its face that drives
the watch by converting light energy into electrical energy.
It is equipped with numerous functions including a perpetual calendar that changes
the year, month and day automatically through February 28, 2100, including leap
years, a time difference correction function that makes it possible to easily change
the time difference without stopping the watch, and a power save function that
reduces current consumption when the solar cell is not exposed to light.

second hands are paused at 12:00 AM, and the hour hand moves continuously
to rapidly advance past the non-existent date.
3. Return the crown to the normal position in synchronization with a telephone
time signal or other time service.
<Correcting Hours and Date>
When the hours (hour hand) are incorrect, the hour hand can be corrected without
stopping the minute and second hands. Since movement of the date is linked to
movement of the hour hand, the date cannot be corrected alone. The date is changed
by correcting the hour hand. The hour hand and date can be corrected for 30
seconds after pressing button (A) or for 30 seconds after the hands have finished
moving.
1. Put the crown in the normal position and press button (A).
* The second hand performs a demonstration movement (forward rotation →
backward rotation →forward rotation).
2. Turn the crown to set the hours.
(1) When turned to the right, the hour hand moves forward by 1 hour (clockwise
rotation).
(2) When turned to the left, the hour hand moves backward by 1 hour (counter-
clockwise rotation).
[Setting the Time and Date]
<Correcting Minutes and Seconds>
1. When the crown is pulled out to the second click, the second hand rapidly ad-
vances to the 0 seconds position and stops.
* Align the hands at the reference position after performing the all-reset proce-
dure when the second hand does not stop at the 0 seconds position.
2. Turn the crown and set the minutes.
(1) When the crown is turned to the right, the second hand makes one revolution
and the minute hand moves forward by 1 minute (clockwise rotation).
(2) When turned to the left, the second hand makes one revolution in the counter-
clockwise direction and the minute hand moves backward by one minute
(counter-clockwise rotation).
* When the crown is turned continuously, the second and minute hands advance
rapidly. Turn the crown to either the left or right to stop the hands from
advancing rapidly.
* Since the movement of the hour hand is linked to movement of the minute
hand, the watch can also be set by rapidly advancing the minute hand.
* Changing of the date is linked to movement of the hour hand. The date is
rapidly advanced automatically when set to a date that does not exist (such as
February 30 or April 31). When the date is advancing rapidly, the minute and

year) and month.
(2) When the crown is turned to the left, the second hand moves backward.
* Turning the crown continuously causes the second hand to advance rapidly.
Turn the crown to the right or left to stop the second hand from advancing
rapidly.
Examples:
* In the case of December in a leap year: Align the second hand at 0 seconds.
* In the case of April in a year that is three years after the most recent leap year:
Align the second hand at 23 seconds (between 4:00 and 5:00).
3. Always make sure to return the crown to the normal position after correcting
the years and month. The second hand catches up to the current seconds and the
hands begin to move.
[When the Date has been Set to a Date that does not Exist]
When the month has been changed and the data has been set to a date that does not
exist after setting the date, the date automatically changes to the first day of the
following month when the crown is returned to the normal position from the cor-
rection state.
* When the crown is turned continuously, the hour hand advances rapidly. Turn
the crown to either the left or right to stop the hour hand from advancing
rapidly.
3. Turn the crown continuously to advance the hour hand rapidly and correct the
date.
* The date changes between the hours of about 10:00 PM and 3:00 AM.
* When the month is set to a month with 30 days, even when the date changes
from the 30th to the 31st, the non-existent date is corrected to the 1st of the
following month by advancing the date rapidly.
Note: When correcting the time, pay attention to AM and PM. The time
when the date has changed is AM.
<Correcting Elapsed No. of Years and Month>
When the crown is pulled out to the 1st click, the second hand switches to display
of the number of years that elapsed since the most recent leap year and the month.
1. When the crown is pulled out to the 1st click, the second hand moves to the year
and month position stored in memory and stops.
2. Turn the crown and set the year and date.
(1) Turn the crown to the right to set the second hand to the position corre-
sponding to the year (number of years elapsed since the most recent leap

Example: Setting the time in London (local time) when the time in Tokyo
(home time) is 10:00 AM:
The time difference between Tokyo and London is -9 hours. Since
it is 1:00 AM in London when it is 10:00 AM in Tokyo, in the case
of correcting the time difference at this time:
1. Press button (A).
2. Turn the crown to the left to turn the hands backward (counter-clockwise) by
9 hours.
Note: If the crown is turned to the right to move the hands clockwise to set the
time to 1:00, the time will be 1:00 PM and the calendar function will not
operate correctly, preventing the date from changing at the proper time.
When button (A) is pressed and the crown is turned, time difference can be cor-
rected in 1 hour units.
The time difference can be corrected for 30 seconds after button (A) has been
pressed or for 30 seconds after the hands finish moving.
1. Put the crown in the normal position.
2. When button (A) is pressed, the second hand performs a demonstration move-
ment (forward rotation →backward rotation →forward rotation).
3. Correct the time difference by turning the crown to the right or left.
(1)When the crown is turned to the right, the hour hand moves forward by one
hour (clockwise rotation).
(2)When the crown is turned to the left, the hour hand moves backward (counter-
clockwise rotation) by one hour.
* Turning the crown continuously causes the hour hand to advance rapidly. Turn
the crown to the left or right to stop the hour hand from advancing rapidly.
Note (1): Pay attention to AM and PM when correcting the time difference.
(2): When returning the time difference to its original setting, return the
hour hand in the opposite direction in which it was corrected.
4. Correcting the Time Difference

1716
The time difference cannot be corrected when the second hand is moving at
two-second intervals indicating that the watch is insufficiently charged. Cor-
rect the time difference after charging the watch by exposing it to light so
that the second hand returns to one-second interval movement.
