Locate the caliber code and the case code by referring to the markings on the case back of your watch.
*The markings are represented as “caliber code – case code”
e.g. 8X42-0AB0-3, 8X53-0AB0-2, 8X82-0AB0-1

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.

2.Next, adjust the time by manual time adjustment.

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.
