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.
Notes Before Use
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).

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.
Your Watch
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.

Tips
Setting the time
When setting the time, determine a.m. and p.m. by the time period•
when the day hand moves.
Advance the minute hand by 4 or 5 minutes past the correct time,•
and then return it to the correct time in order to set the time more
accurately.
Setting the date
The date has a 31-day cycle. Re-set the correct date at the start of
March, May, July, October and December.
Problem Cause and remedy
The second hand moves at
2-second intervals.
The watch has stopped.
The charge is insufficient.
Charge the watch until the second hand moves
at 1-second intervals (p.2).
The day and date change
around noon.
The a.m. and p.m. are reversed.
Set the correct time (a.m. or p.m.), paying
attention to the time period when the day hand
moves (p.8, 11).
The second hand does not
move at 1-second intervals,
even when the watch is
charged.
The watch does not operate
even when charged.
The watch stops soon even
when charged.
Contact your dealer or Citizen Service Center.

WARNING
Water-resistance
performance
There are several types of•
water-resistant watches, as
shown in the following table.
The unit “bar” is roughly equal
to 1 atmosphere.
For correct use within the•
design limits of the watch,
confirm the level of water-
resistance of your watch, as
indicated on the dial and case,
and consult the table.

WARNING Water-resistance performance
Water-resistance for daily use (to 3 atmospheres): This type of watch is water-•
resistant to minor exposure to water. For example, you may wear the watch while
washing your face; however, it is not designed for use underwater.
Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch•
is water-resistant to moderate exposure to water. You may wear the watch while
swimming; however, it is not designed for use while skin diving.
Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of watch•
may be used for skin diving; however, it is not designed for scuba or saturated diving
using helium gas.
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.
