A. BEFORE USING
This watch is powered not by an ordinary battery, but by converting photo
energy to electrical energy.
Before using, expose to light and make sure the watch is sufficiently
charged.
See "G. TIME REQUIRED FOR CHARGING" for charging time reference.
A rechargeable cell is used in this watch to store electrical energy. This
rechargeable cell is a clean energy battery which doesn't use any toxic
substances such as mercury. Once fully charged, the watch will continue
to run for about 6 months without further charging.
To use this watch comfortably, make sure that the watch is always recharged
before it stops.
There is no concern for overcharging this watch. (Overcharge Prevention
Function is included)
We recommend that you recharge the watch everyday.

B. SETTING THE TIME AND DATE
*If the crown is of the screw- type, set the time and calendar after first loosening
the screw. Retighten the screw after the time and calendar have been set.

■Setting the Time
(1) Pull the crown out to the time correction position. (The second hand stops
when the crown is pulled out.)
(2) Turn the crown to set the 24 hour hand and minute hand to the current
time. At this time, the movement of the hour hand is linked with the
movement of the 24 hour hand.
(3) Push the crown back in to the normal position. (The second hand begins
to move when the crown is pushed in.)
(4) Pull the crown out to the date correction position. (1st click position)
(5) Turn the crown to the right (clockwise direction) and set the hour hand to the
current time. Pay attention to AM and PM since the location of the hour hand
where the date changes is approximately 12:00 midnight.
(6) Securely return the crown to the normal position.
Reading the Time Based on a 24-Hour Clock
Read the time on the inside (1:00 to 12:00) with the short hand of the 24 hour
hand, and the time on the outside (13:00 to 24:00) with the long hand.

■Setting the Date
(1) Pull the crown out to the date correction position.
(2) Turn the crown to the left (counter-clockwise direction) and set the date.
(3) Securely return the crown to the normal position.
* Since the date is linked to movement of the hour hand, the date changes
when the hour hand approaches 12:00 midnight. Please note this
operation when using as a dual time watch.
* Do not attempt to correct the calendar when the hour hand is between the
hours of 9:00 PM and 1:00 AM. Setting the calendar during this time may
result in the date not changing on the following day.

C. USING AS A DUAL TIME WATCH
This watch allows the hour hand only to be corrected independently without
stopping the watch. It can be used as a dual time watch by setting the 24 hour
hand and hour hand to different times. After correcting the time, the hour hand
is used to indicate the "local time hours".

■Correcting the Local Time Hours
(1) Pull the crown out to the local time correction position. (1st click position)
(2) Turn the crown to the right (clockwise direction) and set the hour hand to the
desired time. The hour hand can be corrected in +1 hour increments in the
clockwise direction. Set the time while paying attention to AM and PM.
(3) Securely return the crown to the normal position.
* The hour hand cannot be corrected in the counter-clockwise direction. The
date changes when the crown is turned to the left (counter-clockwise). In
addition, since the calendar is linked with the operation of the hour hand, it
may be necessary to correct the calendar after correcting the hour hand
depending on the time to which the hour hand was set.
