Handling the Watch Men's model (A660H)
CAUTION Adjustment of the Date is Not Required.
The date indicated on this watch changes automatically. Since this watch is equipped with a
perpetual calendar function (which changes the date automatically as a result of year, month and
day data, including leap years (February 29), being stored in the memory of this watch prior to
shipment from the factory), it is normally not necessary for the customer to correct the
date.
Since the date is linked with the movement of the hour hand, if the proper procedure is not
performed when setting the time or correcting time difference, the perpetual calendar function
may not operate properly. If the date should happen to not be displayed correctly, reset to the
correct date by referring to Section E of these instructions entitled, “Handling the Watch -
Calender Function”. Furthermore, this watch is equipped with a monitor function that allows
confirmation of month and year settings by pressing the button. If the date is no longer correct as
a result of correcting time difference or other procedure, check the month and year by operating
the button and then reset to the correct date.
However, when the date is completely different from the correct date even after being corrected or the
date does not change properly from the end of the current month to the beginning of the next,
there may be a malfunction. In such cases, please consult Citizen Owners’ Help Desk.

Calendar Monitoring
<Month Monitor>
Month is displayed using the numbers 1 through 12 of the date display.
1. Put the crown in the normal position.
2. The month monitor function is activated by pressing
the button for about 2 seconds. At this time, the
second hand changes from 1-second increment
movement to 4-second increment movement.
• After the date passes the reference position (31st),
the current month is displayed. (It takes about 4-5
seconds for the date to advance by one day. Read
the “month” from the date display after confirming
that the date has definitely stopped.)
* The watch will automatically return to the date display if the button is not pressed for 2-3
minutes after displaying the current month.
<Year Monitor>
Year is displayed using the numbers 1 through 4 of the date display that represent the number of
years that have passed since the most recent leap year.
1. After displaying the current month using the month monitor function, press the button again to
activate the year monitor function.

At this time, the second hand changes to irregular 4-second increment movement in which it
pauses for 3 seconds and then moves 4 steps (4 seconds) in the next second.
• The month display switches to a display of the number of
years that have passed since the most recent leap year.
• The year monitor cannot be activated while the month
monitor is changing (while the date display is moving)
even by pressing the button. Change to the year monitor
function after confirming that the current month is
displayed after operation of the month monitor is
finished and then pressing the button.
* The watch will automatically return to the normal display
if the button is not pressed for 2-3 minutes after
displaying the number of years that have passed since the
most recent leap year.
[Returning the Watch to the Normal Display from the Year Monitor]
After the number of years that have passed since the most recent leap year is displayed, the watch
can be returned to the normal display by pressing the button.

Setting the Calendar
The calendar function used by this watch is a perpetual
calendar that eliminates the need to correct the date on the
last day of the month, including leap years (February 29),
through February 28, 2100 once it has been set.
<Setting the Date>
1. Pull the crown out to position ①.
2. Turn the crown to set the date.
Turning the crown to the right (clockwise) causes the hour
hand to move in the clockwise direction. When the hour hand passes 12:00 midnight, the date advances
by 1 day. Turning the crown to the left (counter-clockwise) causes the hour hand to move in the
counter-clockwise direction. When the hour hand passes 11:00 PM, the date will move back by 1 day.
3. Always make sure to return the crown to the normal position ⓪after setting the date.
* Set the hour hand to the correct time after setting the date.
<Time when the Date Changes>
The time during which the date changes varies according to the direction in which the crown is turned.
• Turning to the right (clockwise): About 12:00 AM
• Turning to the left (counter-clockwise): About 11:00 PM
* Since some time is required until the date wheel begins to move after the hour hand has passed the
time at which the date changes (12:00 AM or 11:00 PM), set the date while checking the manner in
which the date changes.

Time Difference Correction
Time difference can be corrected in 1 hour units without stopping the second
hand.
1. Pull the crown out to position ①.
2. Correct the time difference by turning the crown.
• Turning the crown to the right (clockwise)
enables the time difference to be corrected by
moving the hour hand forward in 1 hour
increments. Turning the crown to the left
(counter-clockwise) enables the time difference
to be corrected by moving the hour hand
backward in 1 hour increments.
* Continue to turn the crown until the hour hand
definitely advances by 1 hour.
* Since the hour hand and date wheel are linked,
correcting the time difference may cause the date
to change if the hour hand passes 12:00 AM (or
11:00 PM).
3. Always make sure to return the crown to the normal position ⓪after correcting time
difference.

[When Time Difference Correction is Required during Overseas Travel]
1. When correcting time difference, set the time and date while paying attention to AM and PM.
(The time when the date changes as a result of the hour hand turning is 12:00 AM.)
2. Since movement of the hour hand and date is linked, when the hour hand is corrected to correct
time difference, the date changes when the hour hand passes 12:00 AM (or 11:00 PM when
turning counter-clockwise). When returning time difference to its original setting, make sure
that the date is also properly corrected.
3. When returning time difference to its original setting, return the hour hand in the
direction opposite that in which correction was made.

18
Example: When the time in Tokyo (home time) is 10:10 AM, the time in London
(local time) is 1:10 AM. Since there is a time difference of -9 hours
between home time and local time, the procedure for correcting this time
difference is as follows:
1. Put the crown in the time
difference correction position.
Move the hour hand while
always making sure to turn the
crown to the left so that the
hour hand moves counter-
clockwise, and set it to 1:00.
☆If the hour hand is set to 1:00 by moving clockwise, the current year and month will no longer
match the year and month stored in the memory of the perpetual calendar, thereby preventing
the date from changing at the correct time.

2. When returning time
difference to the original
setting, return the watch
to that time difference by
always making sure to
turn the crown to the
right so that the hour
hand moves in the
clockwise direction.
☆If the time difference is returned to its original setting by moving the hour hand in the counter-
clockwise direction, the current year and month will no longer match the year and month stored in
the memory of the perpetual calendar, thereby preventing the date from changing at the correct time.
* When the date is completely different from the correct date or the date does not change properly and so
forth, please consult Citizen Owners’ Help Desk.
