Points to be checked
Reception was successful (the reception result is displayed as “Y”), but time has been gained or lost.
Check the time zone setting.
Check the time zone and DST (Daylight Saving Time) settings
If the currently set time zone does not correspond to the region where you are, set the time zone by either of the following operations.
Place where GPS signals can be easily received How to adjust the time zone
Place where GPS signals cannot be received How to manually set the time zone
Check DST (Daylight Saving Time) setting.
Check the time zone and DST (Daylight Saving Time) settings
If DST (Daylight Saving Time) setting does not correspond to the addition conditions of DST (Daylight Saving Time) of the region where you are, set DST (Daylight Saving Time) with reference to Turn ON DST (Daylight Saving Time).
Automatic time adjustment may not get activated for a few days.
Automatic time adjustment
The automatic time adjustment function is unlikely to be activated due to low energy stored in the watch or depending on the environment.
To immediately adjust the time, refer to How to adjust the time zone.
Preliminary position
When the watch is unable to display the precise time or date, or the stopwatch 1/20-second hand or multi-function indicator hand does not point to the correct position even when it has successfully received GPS signals, the preliminary position may be misaligned.
The preliminary position is misaligned due to the following reasons.
Strong impact such as dropping or hitting
Things around you which generate magnetism
Examples of common magnetic products that may affect watches
When comparing the state of “Misaligned Preliminary Hand Position” to that of a weight scale, it is like “a scale which is unable to display the correct weight because its needle is not set to the zero position before weighing.”
Setting the preliminary position of the hour, minute, and seconds hands (automatic hand position alignment function)
The “automatic hand position alignment function” automatically adjusts the hour, minute, and seconds hands when the preliminary positions are incorrect.
The automatic hand position alignment function acts once per 12 hours for the hour hand (at noon and midnight), once per hour for the minute hand, and once per 10 minutes for the seconds hand.
This function works when the preliminary hand position is misaligned due to external factors such as strong impact or magnetic influence.
It does not work to adjust accuracy of the watch or slight misalignment which may occur during the manufacturing process.
The preliminary positions of the hour and minute hands can be adjusted manually.
Setting the preliminary position of the sub-dial, stopwatch 1/20-second hand, multi-function indicator hand, date, and hour/minute hands
Setting the preliminary position of the sub-dial, stopwatch 1/20-second hand, multi-function indicator hand, or date
Since the preliminary positions of the sub-dial, stopwatch 1/20-second hand, multi-function indicator hand, and date are not automatically adjusted, they must be adjusted manually.
Preliminary position of this watch
The preliminary position of the date is “1” (1st).
The preliminary position of the multi-function indicator hand is a charging status display of “low.”
The preliminary position of the hour/minute hands is “12:00 AM”.
The preliminary position for the sub-dial and the AM/PM hand is “12:00 AM”.
The preliminary position of the stopwatch 1/20-second hand is 0.00 seconds.
