B. SETTING THE TIME AND CALENDAR

WW

Setting the time

1. Stop the second hand by pulling out the crown.

2. Turn the crown to set the time.

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

A. BEFORE USING

This watch is not powered by a conventional battery, but is powered by converting light
to electrical energy.

Once fully charged, the watch will continue to run for approximately 6 months without
additional charging. We do recommend exposing your watch to light every day to
ensure optimum performance. Always be sure to recharge the watch before it stops.

Your watch features an Overcharge Prevention Function so there is no need to worry
about overcharging your watch.

A special energy storage cell is used to store electrical energy. This special cell does
not require replacement and is a clean energy unit that does not use any toxic
substances.

Setting the time

1. Stop the second hand by pulling the crown out to the 2nd click (time setting position).

2. Turn the crown to set the time.

Setting the calendar

1. Pull the crown out to the 1st click (calendar setting position).

2. Set the desired date by turning the crown counterclockwise.

3. Set the desired day of the week by turning the crown clockwise.

• In the case of date display models, turning the crown clockwise will result in the loose
play of the crown.

4. After you have set the calendar, be sure to press the crown back to its normal position.

• Do not adjust the calendar when the watch is reading as below. Otherwise the
calendar may not change correctly.

* Date display models ..... between 9:00 pm and 1:00 am

FUNCTIONS OF SOLAR POWERED WATCH

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

If insufficiently charged and time is set

When the watch is exposed to light, the Quick Start Function will begin operating
and the second hand will start moving. The correct time can be set once the watch
is fully charged.

If insufficient charge continues

The second hand changes to a two second
interval movement to indicate insufficient recharging.

Even in such a case, the watch keeps correct time, but about 4
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.)

WW

Overcharge Prevention Function

You can recharge your watch without worry.

Once the special energy storage cell is fully charged, the overcharge prevention
function comes into operation and prevents over-charging of the energy storage cell.

D. CARE AND HANDLING DURING CHARGING

WW

Notes on Use

To maintain optimal performance, be sure to expose your watch to light regularly.

Please note that if you wear long sleeves, your watch may be hidden from light and
may result in insufficient charging. As such, additional exposure to light may be
necessary.

• When you take your watch off, be sure to place it in as bright an area as possible.

WW

Notes on recharging

• Avoid recharging your watch in areas of high temperatures (over about 60 °C /
140 °F), otherwise the sensitive components of the watch may become damaged.
(e.g.) Incandescent lights generate heat sufficient to damage your watch. Be sure to

keep the watch at least 50cm (20inches) away from the bulb so no damage
occurs. We do not recommend the use of Halogen bulbs for recharging.

Never place your watch on the dashboard or rear deck of a vehicle as the heat
generated in these areas can damage your watch.

E. ABOUT THE ENERGY STRAGE CELL

Unlike ordinary watches, the special energy storage cell used in your watch does
not need regular replacement. This is a clean energy cell that will last the life of
the watch.

CAUTION:

The energy cell should last the life of the watch. Never allow anyone other than an
Authorized Service Center to replace this cell. The movement is designed to operate
with only the original energy storage cell. If an alternate cell is installed, such as a
conventional battery, the battery may become overcharged resulting in damage to the
movement and/or bursting of the cell, which could cause injury to the user.
