Auto Hand Home Position Correction
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 hand home position
correction corrects the hand position automatically.
• Auto correction is performed in the Timekeeping Mode only.
• The auto correction operation corrects the positions of the second, minute, and hour
hands. Home position correction of the dial hands and day must be performed
manually, using the procedure under "Manual Home Position Correction" (page
E-48).
• Each hour, the watch performs automatic correction of the hand positions.
Correction can be performed for error up to 55 minutes slow or 5 minutes fast.
• You also can trigger the auto hand home position correction operation manually, if
you want. See "To trigger the auto hand home position correction operation
manually" (page E-46) for more information.
• The auto hand home position correction operation can take up to three and a half
minutes to complete.
• If you release D when the second hand stops the first time (after about three
seconds) in the above operation, the watch will enter the manual home position
correction mode, which is described under "Manual Home Position Correction" (page
E-48). If this happens, press A to return to the Timekeeping Mode and then perform
the above operation again.
The manually triggered auto home position correction operation 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.
• Each press of C cycles through available settings in the sequence shown below.
