* Coordinated Universal Time, the world-wide scientifi c standard of timekeeping.
The reference point for UTC is Greenwich, England.
• Selecting some city codes automatically makes it possible for the watch to receive the time
calibration signal for the corresponding area. See page E-20 for details.

Hand Home Position Adjustment
If the watch is exposed to strong magnetism or impact, its hands can go out of alignment with the time on
the digital display. This can result in incorrect time indication even though a time calibration signal is being
received. Your watch has an auto hand position correction feature that normally adjusts the hands. Should
you notice that the hand positions are not correct, perform the operation below to correct them manually.
To adjust home positions
1. In the Timekeeping Mode, pull out the crown.
2. Hold down
A
for at least fi ve seconds until
HAND SET
fl ashes and
then
HAND ADJ
appears on the digital display.
• This will start home position adjustment, which causes all of the
watch hands to move to 12 o’clock.
• After the hands stop moving, will appear on the digital
display.
Important!
• Before performing step 3, below, make sure that all hands have
returned to the 12 o’clock position. Pushing the crown back in
while any hand is not at the 12 o’clock position will not perform
home position adjustment.
3. Push the crown back in.
• This will cause all of the hands (small hand, hour hand, minute
hand, second hand) to return to their normal positions.
Note
After performing home position adjustment, enter the Timekeeping Mode and check to make sure that the
analog hands and the display indicate the same time. If they do not, perform home position adjustment
again.
Wait until all of the hands
move to 12 o'clock.
