"Official time zones around the world are subject to change depending on government policy of each country or region.
This product is designed so that the performance can be provided based on the time zone information at the following time:
Caliber 7X52-mounted watch: January 2012
Caliber 8X82-mounted watch: January 2014
In a region where the official time zone is changed after the time above, even if the time zone is adjusted by receiving GPS signals, the correct time cannot be displayed. Please carry out the following operations to display the correct time:
< To set the time of this watch in a region where the official time zone is changed >
1.Select the time zone appropriate for the current time in the target region by manual time zone setting.
For details, please refer to “Basic Manual (caliber 7X52-mounted watch)” or “Handy Manual (caliber 8X82-mounted watch).”
2.Next, adjust the time by manual time adjustment.
For details, please refer to “Basic Manual (caliber 7X52-mounted watch)” or “Handy Manual (caliber 8X82-mounted watch).”
3.To continue to use the watch in the same time zone, correct time can always be displayed by automatic time adjustment or manual time adjustment, unless the time zone setting is changed.
4.When moving from a region where the official time zone is changed to a region of another time zone, if you adjust the time zone of the watch to the second region, when you return to the original region, carry out the same operation from 1 to 3 above to display the correct time in the original region."
Короче, выставляйте правильное время вручную
