■ Q&A for the world time function
Q : Will the watch be automatically set to the local time when it is moved to a place outside Japan in a different time zone?
A : The watch will not be automatically set to the local time if it is just moved to a place outside Japan in a different time
zone.
When traveling abroad, select the time zone for that area.
The watch automatically displays the local time when the time zone is selected. (The time difference can be adjusted
in one-hour increments.)
After selecting the time zone, radio signals within the radio signal reception range are received and a more accurate
local time can be set. (The transmitting station from which to receive radio signals is changed by selecting the time
4
zone.)
Q : When returning to Japan from overseas, is the time automatically set to Japan time?
A : Just moving does not adjust your watch to Japanese local time.
When wearing a watch in Japan, set to Japan time by use of the world time function.
Q : The hands stop during operation of time zone selection setting, therefore, does time lag occur?
A : The internal circuit stores the time, therefore, no time lag occurs.
Q : When a time zone for a region other than 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 zone 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, refer to "How to manually set the time" → P.73
