1. FEATURES
This watch is a solar-powered watch that contains a solar cell in its face that
drives the watch by converting light energy into electrical energy. It is
equipped with numerous functions including a full-auto calendar that changes the
date automatically (day, month and year change automatically through February 28,
2100 including leap years), a daily alarm function that can be set based on a 24-
hour clock, and a chronograph function that allows measurement of time in 1120
second units up to 59 minutes, 59.95 seconds.

3. BEFORE USING
A rechargeable battery is used in this watch to store electrical energy. This
rechargeable battery is a clean energy battery that does not contain mercury or
other toxic substances. Once fully charged, the watch will continue to run for
about 9 months without additional charging (when the power save feature is
operating). This rechargeable battery is not a user replaceable item.
This watch is a solar-powered watch. Before using this watch, expose its
solar cell to light sufficiently to charge its rechargeable battery.
If this watch has stopped running because of insufficient charge of this
rechargeable battery, recharge this battery by exposing the solar cell to
strong light such as the sunlight.
• Power Save Feature
When power generation stops as a result of light not shining on the solar cell
during the time display or local time display, the second hand stops at the 12:00
position and only the hour and minute hands move to save power. When light once
again begins to shine on the solar cell, the second hand advances rapidly to the
current seconds and returns to moving at one second intervals. If light (several
tens of luxes) does not shine on the solar cell for continuous 15 seconds (this
period depends on the design, however) and the second hand comes to the 12:00
position, the watch enters the power save mode.
<How to Use This Solar-Powered Watch Properly>
To use this watch comfortably, make sure to recharge it before it stops running
completely. Since there is no risk of overcharging (Overcharging Prevention
Feature), it is recommended that the watch be recharged everyday.

5. FUNCTIONS UNIQUE TO SOLAR-POWERED WATCHES
When the watch becomes insufficiently charged, the following warning features
will be activated to inform the wearer that the watch is insufficiently charged.
<Insufficient Charging Warning Feature>
Regardless of the display of the watch at the time, when the watch becomes
insufficiently charged, the watch changes to the time display and the second hand
moves to the CHARGE position to inform the wearer that it is insufficiently
charged. After the second hand moves to the CHARGE position, the watch changes to
the time display in the order of the 24-hour hand, hour hand, minute hand and
date wheel (function hand). Although the watch continues to keep time accurately
at this time, the watch stops after about 5 days have elapsed (roughly 2 days in
the case the hands have been moved to switch the time when the insufficient
charging warning feature is activated).
When this happens, charge the watch by
exposing to light so that it returns to
one-second-interval movement. However,
since the time is incorrect when the
watch is exposed to light and changes
to the insufficient charging warning
display after it has stopped due to
insufficient charging, set the time
after sufficiently charging the watch.

Notes
:
• Chronograph measurement stops and the chronograph is reset even when
measurement is in progress.
• The set time (time difference) is retained for the local time.
• The alarm will not sound even if it is set.
• Crown (mode switching) and button operations will not function.
<Time Setting Warning Feature>
When the watch is recharged by exposing to light after it has stopped, the second
hand moves to the SET position to inform the wearer that the time is incorrect.
Although the 24-hour hand, hour hand and minute hand will begin to move after the
second hand moves to the SET position, since the time is incorrect, reset the
time and date after sufficiently charging the watch.
<Overcharging Prevention Feature>
Notes:
• Crown and button operations will not function
except for time and calendar setting operations.
• When the crown is pulled out to position 2 (time
correction position) in the time or date setting
mode, the time setting warning feature is
canceled. The second hand will remain stopped at
the SET position unless the crown is pulled out
to position 2 and the time is set.
•
In the case the watch has stopped due to
insufficient charging, a minimum of 30 minutes
are required until the watch changes to the time
setting warning display even if sufficiently
exposed to light.
The overcharging prevention feature is activated when the secondary battery is
full charged so that it is not charged further.
<Power Save Feature>
When power is no longer generated as a result of light not shining on the solar
cell when the watch is in the time/calendar mode or local time mode, the second
hand moves to the 0 seconds position and stops to save power by reducing current
consumption.
The 24-hour hand, hour hand and minute hand continue to keep the correct time
even though the second hand is stopped. Furthermore, the calendar is corrected in
coordination with the 24-hour hand, hour hand and minute hand.
During normal hand movement, when power generation is
resumed after the second hand stops at the 0 seconds
position, the second hand is rapidly advanced to the
correct seconds and begins one-second interval
movement. However, when the insufficient charging
warning feature has been activated, the second hand
moves to the CHARGE position and stops, and when the
time setting warning feature has been activated, it
moves to the SET position and stops. When the watch has
stopped, the second hand moves to the STOP position and
remains stopped.
Note:
During the time the rechargeable battery is fully charged and the
overcharging prevention feature is operating, the power save feature does not
operate even when power generation is interrupted as a result of not exposing the
solar cell to light. Similarly, the power save feature will also not operate when
the secondary battery has temporarily become fully charged as a result of
exposure to intense light.
