Notes Before Use
Notes on charging your watch
This watch has a rechargeable cell which is charged by
exposing the dial to light such as direct sunlight or fluorescent
lamps.
2 3
For optimal performance
Expose the watch with the dial towards direct sunlight for several hours at least •
once a month.
After taking off the watch, put it in a position so that the dial is exposed to •
bright light, such as by a window.
Before storing the watch in a dark place for an extended period of time, be sure •
to charge it fully.
When the watch is regularly covered with long sleeves, it may not be charged
sufficiently. Try to keep the watch exposed to light sufficient for charging.
Do not charge the watch at a high temperature (about 60°C/140°F or higher).
English
Your Watch
Eco-Drive (solar
powered) watch
The watch operates by
converting sunlight and other
light into electrical energy.
Once the rechargeable cell is
fully charged, the watch will
function for approximately
6 months.
4 5
Insufficient charge warning
If the power becomes
very low, the second hand
advances at 2-second
intervals, indicating that
charging is necessary.
When the second hand
starts to advance at
2-second intervals, expose the watch to light
until it is fully charged.
If the watch is not exposed to light within
approximately 4 days after the insufficient
charge warning starts, the watch will stop.
Quick start function
When the stopped watch is exposed
to light, it starts operating again
immediately.
After quick start, expose the watch to
light until it is fully charged. Set the
correct time before using the watch.
Overcharging prevention
function
Once the watch is fully charged, an
overcharging prevention function will
automatically activate so that it is not
charged any further.
No matter how much the watch
is charged, it will not affect the
rechargeable cell, time accuracy,
functions or other performance.

CAUTION
Be sure to use the watch with the crown pressed in (normal position). If your watch •
has a screw down crown, be sure to tighten the crown completely.
Do NOT operate the crown or button with wet fingers or when the watch is wet. •
Water may enter the watch and compromise water-resistance.
If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry •
cloth.
If moisture has entered the watch, or if the inside of the crystal is fogged up and does •
not become clear within a day, immediately take the watch to your dealer or Citizen
Service Center for repair. Leaving the watch in such a state will allow corrosion to
form inside.
If seawater enters the watch, place the watch in a box or plastic bag and immediately •
take it in for repair. Otherwise, pressure inside the watch will increase, and parts
(crystal, crown, buttons, etc.) may come off.
17
Precautions
English
CAUTION
Leaving dust and dirt deposited between the case and crown may result in difficulty •
in pulling the crown out. Rotate the crown while in its normal position, from time to
time, to loosen dust and dirt and then brush it off.
Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited •
dust and dirt may cause corrosion and soil your clothing. Clean the watch
occasionally.
Keep your watch clean
Cleaning the Watch
Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal.•
Use a soft, dry cloth to wipe off perspiration and dirt from the leather band.•
To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and •
water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band.
If your watch is not water-resistant, take it to your dealer.
Note: Avoid using solvents (thinner, benzine, etc.), as they may damage the finish.
18
CAUTION
Use the watch within the operating-temperature range specified in the instruction •
manual. Using the watch where temperatures are outside the specified range, may
result in deterioration of functions or even stoppage of the watch.
Do NOT use the watch in places where it is exposed to high temperature, such as in a •
sauna. Doing so may result in a skin burn.
Do NOT leave the watch in a place where it is exposed to high temperature, such as •
the glove compartment or dash-board of a car. Doing so may result in deterioration of
the watch, such as deformation of plastic parts.
Do NOT place the watch close to a magnet. Timekeeping will become inaccurate if •
you place the watch close to magnetic health equipment such as a magnetic necklace
or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a
mobile phone. If this has occurred, move the watch away from the magnet and reset
the time.
Do NOT place the watch close to household appliances that generate static electricity. •
Timekeeping may become inaccurate if the watch is exposed to strong static
electricity, such as is emitted from a TV screen.
Operating environment
19
Precautions
Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.•
Avoid using the watch in an environment where it may be exposed to chemicals or •
corrosive gases. If solvents, such as thinner and benzine, or substances containing
such solvents come in contact with the watch, discoloration, melting, cracking, etc.
may result. If the watch comes in contact with mercury used in thermometers, the
case, band or other parts may become discolored.
English
Periodical inspections
Your watch needs inspection once in every two or three years for safety and long use.
To keep your watch water-resistant, the packing needs to be replaced regularly.
Other parts need to be inspected and replaced if necessary.
Ask for Citizen genuine parts upon replacement.
