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.

Preliminary position
When the watch is unable to display the precise time or date, or the sub
dial, or 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
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.”
Adjusting the preliminary position of the hour, minute
and second hands (Automatic hand position adjustment
function)
The hour, minute and second hands have an “automatic hand position adjustment function,”
which automatically corrects an incorrect preliminary position.
The automatic hand position adjustment function is activated once a minute for the second hand
and at 12:00 both for the AM and PM for the hour and minute hands.
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 position of the hour and minute hands can be manually adjusted.

Adjusting the preliminary position of the sub dial, date,
and indicator hand
Since the preliminary position of the sub dial, date, and indicator hand is not
automatically adjusted, it must be adjusted manually.
