Auto Correction of Hand Home Positions

Strong magnetism or impact can cause the hands and/or day setting to be off, even
if the watch is able to perform the signal receive operation. Auto correction of hand
home positions correct the hand position automatically.
Auto correction is performed in the Timekeeping Mode only.
Auto correction corrects the positions of the z Hour Hand, c Minute Hand,
and x Second Hand. For the dial hands and day, you must perform the manual
adjustment procedure under "Adjusting Home Positions Manually" (page E-55).
Each hour, the watch performs automatic correction of the hand positions from
–55 minutes to +5 minutes.
You also can trigger auto correction of hand home positions manually, if you
want. See "To trigger auto correction of hand home positions" (page E-53) for more
information.
Auto correction of hand home positions can take up to three and a half minutes to
complete.

above operation again.
Manually triggered auto correction of hand home positions performs the following
two steps.
1. The hands will move automatically in order to determine the home positions of the
watch.
2. After the hand home positions are determined, the watch will return to normal
timekeeping automatically. This completes the correction operation.
