When power drops to Level 3, all functions will be disabled but the watch willx
continue to keep time internally for about one week. If you recharge the battery
sufficiently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.

Power Levels
You can get an idea of the watch’s power level by
observing the movement of the
x
Second Hand in the
regular timekeeping.
If the
x
x
Second Hand is moving normally at one-second
intervals, power is at Level 1.
If the
x
x
Second Hand is moving at two-second intervals,
power is at Level 2, which is quite low. Expose the
watch to light as soon as possible so it can charge (Low
battery alert).
Moves at two-second

Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the following conditions for long periods.
On the dashboard of a car parked in direct sunlight
x
Too close to an incandescent lampx
Under direct sunlightx
Important!
Keep the watch in an area normally exposed to bright light when storing it for long
x
periods. This helps to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in
x
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.
E-6
Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.
Best charging
x
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
make sure that its face is
not blocked from light by the
sleeve of your clothing.
The watch may enter a
x
sleep state (page E-11) if
its face is blocked by your
sleeve even only partially.

Hand Home Position Adjustment
Strong magnetism or impact can cause the hands of the watch to be off.
If this happens, perform the applicable home position adjustment procedures in this
section.
Hand home position adjustment is not required if the time and day settings are
x
correct.
Important!
It can take up to 14 minutes for the hands to move to their home positions for hand
x
home position adjustment. It also can take up to 14 minutes for the hand to return to
their normal positions following hand home position adjustment.
If you need to move a hand to the left, move it past the correct home positions and
x
then use Cto move back to the right. This helps to ensure better home position
adjustment accuracy.

To adjust the Moon phase indicator setting
Hold down Bfor about one second to advance the
n

times as necessary until the phase is indicated correctly.
Holding down

Adjustment of thex
n
Moon Phase Indicator is
recommended on a day that there is a full Moon or
a new Moon, since the current phase is easiest to
determine on these days.

Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-9). Continue exposing
the watch to light until the
x
Second Hand starts moving normally (at one-second
intervals).
■ The
x
Second Hand starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not sufficiently charged yet. Continue keeping it exposed to
light.

Troubleshooting
Hand Movement and Position
■ The
x
Second Hand is moving at two second intervals.
■ All regular timekeeping hands are stopped at 12 o’clock and none of the
buttons work.
Power may be low. Expose the watch to light until the
x
Second Hand starts moving
normally, at one-second intervals (page E-8).
■ The hands of the watch suddenly start moving at high speed, even when I do
not perform any operation.
The hand movement does not indicate malfunction, and should stop shortly.
The watch is recovering from a sleep state (page E-11).
■ The hands are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand alignment. Adjust the watch’s hand
home position alignment (page E-16).
