■ Make sure to keep the watch suffi ciently 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 suffi cient. Place or store in a location
receiving light, etc., to suffi ciently charge electricity.
■ T he amount of energy stored in the watch can be checked by the
movement of the second hand.

This solar-drive and radio-controlled watch is equipped with a radio signal adjustment function.
・ B y selecting a time zone or a time diff erence, the watch can display the local time of the
selected area around the world.
・ T he watch is operated by using electric energy which is converted from the light
received by the solar panel.
・ T his watch displays the precise time by receiving radio signals conveying time information.
It can receive offi cial 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 ･･････････････････ By selecting a time zone or a time diff erence, the watch can
→ P.120 display the local time of the selected area around the world.
■ Radio Signal Receiving Function ･････････ T his watch adjusts the time and the date precisely by automatically
→ P.104 receiving radio signals daily.
I n addition, radio signals can be forcibly received with manual operation.
T his watch can receive offi cial standard radio signals from Japan (from

■ To receive radio signals
The watch automatically receives radio signals to adjust the time
every day.
Automatic radio signal reception is carried out before two and four
o'clock during the night.
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.111
■ Display Function of Radio Signal Reception Level ･･･ The movement of the second hand indicates the radio signal reception
→ P.148 level during radio signal reception attempts. (only manual reception)
■ Display Function of Radio Signal Reception Results ･･･ The movement of the second hand indicates radio signal reception
→ P.114 results (Yes/No).
■ Solar Charging Function ･････････････ A solar cell underneath the dial converts any form of light
→ P.116 into electrical energy to charge it. Once fully charged,
the watch continues to run for approximately six months.
■ Energy Depletion Forewarning Function ･･･ The movement of the second hand indicates that the
→ P.118 battery should be charged.
■ Power Save Function ･･････････････････ This watch is equipped with a function which can
→ P.119 suppress energy consumption when it is left without
receiving an adequate light source for a certain
length of time.
■ Automatic Hand Position Alignment Function ･･･ When the hand positions display an incorrect time as
→ P.156 a result of external infl uences such as magnetism, the
watch automatically corrects the hand misalignment.
