We recommend seeking the assistance of an experienced watch technician for sizing of your

leading to loss of your watch or injury.
Consult Citizen Owners’ Help Desk.

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.
