Band adjustment
We recommend seeking the assistance of an experienced watch technician
for sizing of your watch. If adjustment is not done correctly, the bracelet may
unexpectedly become detached leading to loss of your watch or injury.
Consult your nearest authorized Citizen service center. Other shops may charge
for, or may not provide, the service.
Protective stickers
Be sure to remove any protective stickers that may be on your watch (case back,
band, clasp, etc.). Otherwise, perspiration or moisture may enter the gaps between
the protective stickers and the parts, which may result in a skin rash and/or
corrosion of the metal parts.

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 (refer to page 16 for charging guidelines).
For optimal performance, be sure to:
•
Put the watch in a location where the dial is exposed to bright
light such as by the window even when it is not used.
•
Expose its dial to direct sunlight for 5 or 6 hours at least
every half-a-month.
•
Avoid leaving it in dark places such as in a drawer for long
periods of time.

CAUTION
• This watch contains a large-capacity rechargeable cell for performing powerconsuming satellite signal reception. This large capacity cell takes more time to
charge than those found in other Eco-Drive watches.
• If the surrounding temperature falls below 0°C (32°F) or exceeds 40°C (104°F),

charging will not be possible.
• Do not charge the watch at a high temperature (about 60°C (140°F) or higher)
as doing so may cause movement malfunction.
• If the watch is obscured from light by long sleeves frequently, supplemental
charging may be needed to ensure continual operation.
• The watch stops charging automatically after finishing (overcharging prevention
function). The function prevents damage to performance of the watch and

When the watch reaches a low charge state (insufficient charge warning
function)
When the power reserve becomes low, the second hand
moves once every two seconds. This is the insufficient charge
warning function. Be sure to fully charge your watch as
outlined on page 16.
• When the watch is sufficiently charged, the second hand
will move normally.
• If you do not charge the watch for 5 days or longer after the insufficient charge
warning movement has begun, the watch will be depleted of all power and stop.
CAUTION
•
If you do not charge the watch for 30 days after it has stopped, recharging will
not be possible (over discharge detection function).
Consult your nearest authorized Citizen service center if no hands start to move
even after charging a stopped watch for one day or more exposing to direct
sunlight.

CAUTION
• The level of power generation amount indicated is that of the moment you
engage this function. The level indication does not reflect any change in power
generation after engaging this function.
• The level may vary even under the same brightness due to the entry angle
of light to the dial of the watch or other elements. The level may also vary
depending on difference of models.
• The indication level “6” of power generation amount corresponds to generation
in cloudy outdoors (about 10 000 lx illuminance) or a brighter location.
