■ Questions and answers regarding time difference adjustment function
Ｑ： When returning to Japan from overseas, is the time automatically set to Japan time?
Ａ： Just moving cannot adjust the time to Japan time. After setting the time
difference, radio signal reception is not performed. When wearing a watch in Japan,
set to Japan time by use of the time difference adjustment function.
Ｑ： The hands stop during operation of time difference setting, therefore, does time lag occur?
Ａ： The internal circuit stores the time, therefore, no time lag occurs.
Ｑ： When a time difference for regions out of the radio signal reception range is set, the
watch will not receive a radio signal. How is the accuracy of the watch at that time?
Ａ： The watch has an accuracy of a normal quartz watch in that case. (Monthly rate: ±
15 seconds)
Ｑ： How is adjustment made to a local time with a time difference of 15 minutes or 30 minutes?
Ａ： The time can be adjusted on a 1 hour basis by use of the time difference adjustment function.
When adjusting to a local time with a time difference of 15 minutes or 30 minutes, please
refer to the " How to manually set the time " on P.143.

Time Difference Adjustment (when using the watch overseas)
■ Features of time difference adjustment function
・ Set the time difference in the time difference
adjustment mode to display an overseas local time.
The watch can display an overseas local time in one hour units.
The time difference is set based on UTC (Coordinated Universal Time).
The range of time differences around the world based on UTC is from
−11 hours to +13 hours.
・ In the time difference adjustment mode, the time
difference based on UTC (Coordinated Universal
Time) is displayed by the position of the second hand.
Operate the buttons to point the second hand to the
desired position for setting of the time difference.
・ A radio signal transmitting station is selected
by setting the time difference.
Examples: When using the watch in Japan, set the second hand to the nine
second position: Tokyo to receive a radio signal from Japan.
When using the watch in China, set the second hand to the
eight second position: Beijing.
When setting the time difference for a region other than the radio signal
reception ranges, the radio signal reception function will not work.
