A. BEFORE USING

This watch is powered not by an ordinary battery,
but by converting photo energy to electrical energy.

A secondary battery is used in this watch to store
electrical energy. This secondary battery is a

clean energy battery which does not 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 risk of overcharging this watch.
(Overcharging Prevention Function is provided.)

We recommend that you recharge the watch
every day.

B. SETTING THE TIME AND DA TE

* If the crown is of the screw-type, set the time and

date after first loosening the screw. Retighten the
screw after the time and date have been set.

■ Setting the time

1. Stop the second hand at the 0 second position by
pulling the crown out to the 2nd click.

2. Turn the crown to set the time.

3. After setting the time, firmly push the crown back
in to its normal position.

■ Setting the date

1. Pull the crown out to the 1st click.

2. Set the desired date by turning the crown.

• Do not adjust the date when the watch display is

reading between 9:00 pm and 1:00 am, otherwise
the date might not change on the following day.

3. After you have set the date, be sure to firmly
return the crown to its normal position.

Please make sure to check the following
before use.

Please read carefully section G entitled “IF YOUR
WATCH IS A DIVER’S WATCH” to ensure proper
use of the watch in the case your watch is a
diver’s watch.
If your watch is a diver’s watch, the words “AIR
DIVER’S 200M” are indicated on the case back
(or dial).
If the words “AIR DIVER’S 200M” are not
indicated on the case back (or dial) of your
watch, this means that your watch is not a diver’s
watch and should not be used for scuba diving.

Before using, expose to light and make sure
the watch is sufficiently charged.
See “F.TIME REQUIRED FOR CHARGING” for
reference charging times.

C. FUNCTIONS OF SOLAR POWERED WATCHES

If the charge becomes insufficient, a warning
function will operate and the display changes as
shown below.

■ Insufficient Charge Warning Function
The second hand changes
to a two second interval
movement to indicate
insufficient recharge.

Even in such a case, the
watch keeps correct time, but
about 3 days after the two
second interval movement
begins, the watch will stop.
After exposing the watch to
light recharging takes place
and the watch returns to one second interval
movement.

■ Quick Start Function

The watch will stop if it is completely discharged.

It will begin to operate soon after it is exposed
to light.

(However, the time to start may vary according to
the brightness of the light.)

■ Time Setting Warning Function

If the watch stops, subsequent exposure to light
allows the Quick Start Function
to start again, and the second

hand moves with a hitch to
indicate that the time is
correct.

In this case, quickly recharge
the watch and reset the time.
Otherwise, the hitch movement
will continue.

■ Overcharge Prevention
Function
There is no risk of overcharging.

Once the secondary battery is fully recharged, the
overcharging prevention feature comes into
operation and prevents overcharging.
