CAUTION
Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch.
* If the inner surface of the glass is clouded with condensation or water droplets appear
inside of the watch for a long time, the water resistant performance of the watch is
deteriorated. Immediately consult the retailer from whom the watch was purchased or
SEIKO CUSTOMER SERVICE CENTER.
Do not leave moisture, sweat and dirt on the watch for a long time.
Be aware of a risk that a water resistant watch may lessen its water resistant
performance because of deterioration of the adhesive on the glass or gasket, or
the development of rust on stainless steel.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring may accelerate the
deterioration of water resistant performance of the watch.

HOW TO USE
Before use
■ Make sure to keep the watch sufficiently charged
The watch operates while charging electricity by converting light received on the dial to electrical energy.
It cannot properly operate unless the remaining energy is sufficient.
Place or store in a location receiving light, etc., to sufficiently charge electricity.
■ The amount of energy stored in the watch can be checked by the
movement of the small seconds hand.
“Checking the Charging Status” → P.16
■ Charging the solar battery
“How to charge the battery” → P.48
“Guide to charging times” → P.49
■ To receive radio signals
The watch automatically receives radio signals to adjust the time every day.
Automatic radio signal reception is carried out before 2:00 AM, 3:00 AM and 4:00 AM.
During this period of time, place the watch in a location that easily receives radio signals without wearing
it and do not move it.
“To improve radio signal reception” → P.25

HOW TO USE
Characteristics
This solar-drive and radio-controlled watch is equipped with a world time function.
• The time in each region of the world can be displayed by selecting the time zone.
• This watch displays the precise time by receiving radio signals conveying time information.
• It can receive official standard frequencies from Japan (from either of two transmitting stations), the
People’s Republic of China, the United States of America and Germany.
■ World Time Function................
→ P.30
The time in each region of the world can be displayed by selecting
the time zone.
■ Radio Signal Receiving
Function....................................
→ P.18
This watch adjusts the time and the date precisely by automatically
receiving radio signals daily.
In addition, radio signals can be forcibly received with manual operation.
This watch can receive official standard radio signals from Japan (from 2
transmitting stations), China, U.S.A. and Germany (the transmitting station
for receiving radio signals can be selected using world time function).
■ Reception Level Indication
Function....................................
→ P.80
The movement of the small seconds hand indicates the radio signal
reception level during radio signal reception attempts.
(Only manual reception)
■ Display Function of Radio
Signal Reception Results........
→ P.28
The movement of the small seconds hand indicates radio signal
reception results (Yes/No).

HOW TO USE
■ Stopwatch function..................
→ P.38
The stopwatch can carry out measurements up to 60 minutes in
increments of 1/5 of a second.
When the measurement reaches 6 hours, the stopwatch
automatically stops counting.
■ Solar Charging Function..........
→ P.48
A solar cell underneath the dial converts any form of light into
“electrical energy” to charge it. Once fully charged, the watch
continues to run for approximately six months.
■ Energy Depletion
Forewarning Function...........
→ P.50
The movement of the small seconds hand indicates that the battery
should be charged.
■ Power Save Function...............
→ P.51
This watch is equipped with a function which can suppress energy
consumption when it is left without receiving an adequate light
source for a certain length of time.
■ Automatic Hand Position
Alignment Function..................
→ P.86
When the hand positions display an incorrect time as a result of
external influences such as magnetism, the watch automatically
corrects the hand misalignment.
