Preliminary position
When the watch is unable to display the precise time or date, or the sub-dial, day hand 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
Things around you which generate magnetism
→ Examples of common magnetic products
that may affect watches P. 35
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, second, and
indicator hands (Automatic hand position adjustment function)
The hour, minute, second, and indicator hands have an “automatic hand position adjustment
function,” which automatically corrects an incorrect preliminary position.
The automatic hand position adjustment function is activated once every 12 hours (12:00 AM and
PM) for the hour hand, once an hour for the minute hand, once a minute for the seconds hand, and
once every 24 hours (12:00 AM) for the indicator 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, minute, and indicator hands can be manually adjusted.
→ Adjust the preliminary position of the sub-dial, day hand, date, indicator hand, and hour/minute hands
P. 46
Adjusting the preliminary position of the sub-dial, day hand, and date
Since the preliminary positions of the sub-dial, day hand, and date are not automatically adjusted,
they must be adjusted manually.
→ Adjust the preliminary position of the sub-dial, day hand, date, indicator hand, and hour/minute
hands P. 46
When the sub-dial, day hand, date, indicator hand or hour/minute/seconds hand position is misaligned
