The watch may be in the power recovery mode (page E-16). Do not perform any
operation until the hands return to their normal positions (in about 15 minutes). The
hands should return to their correct positions when normal operation returns. To help
power recover, leave the watch in a location where it is exposed to light.

Auto correction corrects the positions of all hands. For the day Indicator, you must
perform the manual adjustment procedure under "To adjust home positions" (page
E-65).
If the v Upper Dial Hand is 12 hours off of the current correct time, correct the
setting using the procedure under "To adjust home positions" (page E-65).

the night, while the watch is in the sleep state (page E-18).

Troubleshooting
Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to "Mode Reference Guide" (page E-32). To return directly to the Timekeeping
Mode, hold down C at least two seconds.
■ The x Second Hand is moving at two-second intervals.
■ All the watch's hands are stopped at 12 o'clock and none of the buttons work
(x Second Hand stopped at 57, 58, 59, or 00).
Power may be low. Expose the watch to light until the x Second Hand starts moving
normally, at one-second intervals (page E-15).
■ The hands of the watch suddenly start moving at high speed, even when I do
not perform any operation.
This could be due to any one of the following causes. In all cases, the hand movement
does not indicate malfunction, and should stop shortly.
The watch is recovering from a sleep state (page E-18).
The period when summer time is applied in the location where you are using the
watch may be different from the period set for your currently selected Home City.
Use the procedure under "To switch between standard time and summer time
manually" (page E-39) to switch from AUTO to STD (for standard time) or DST (for
summer time).
■ The time and date settings are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand and day indicator alignment. Adjust the
watch's hand and day indicator home position alignment (page E-63).
The z Hour Hand will also move.
See "Using the Crown" (page E-3) for information about high-speed hand
