About Eco-Drive Watches
• is Eco-Drive watch features a solar panel under the dial and is powered by
converting solar energy into electrical energy.
• This watch also features functions such as a perpetual calendar ( which
automatically adjusts the date at month ends and leap years) a daily alarm
(that can be set according to a 24-hour system), and a chronograph (capable
of measuring up to 59 minutes, 59.95 seconds, in 1/20 second units).

56
• Periodically expose the watch dial to daylight
is watch uses a rechargeable cell to store electrical energy. is is an
environmentally clean cell that does not use any harmful substances such as
mercury.
Once the rechargeable cell is fully charged, (and the power saving feature
is operative) the watch will function for approximately 2 years without
additional exposure to light.

57
• For optimal performance
For optimal performance, perform the following:
• Expose the watch with the dial facing towards direct sunlight for ve to six
hours at least once a month.
• Avoid leaving the watch in a dark place for long periods of time.
• When the watch is regularly covered with long sleeves, it may not be
charged suciently. Try to keep the watch exposed to light sucient
for charging.
• Do not charge the watch at a high temperature (about 60ºC or higher).

58
Guide to Charging Time
Below are the approximate times needed for charging when exposing the
watch dial to light continuously.
Please use this table as a reference only.
＊ To charge the rechargeable cell fully, it is recommended to expose the dial to direct
sunlight. A uorescent lamp or interior lighting does not have sucient illumination to
charge the rechargeable cell fully.

60
If the watch becomes insuciently charged, the second hand will
automatically move to the low charge warning, informing you of a
“Charge warning” and “Time setting warning”.
Always take care to charge your watch so that the charge does not become
insucient.
[Normal time display]
If watch becomes insuciently charged
As the watch recharges
If the second hand points to the SET position, it indicates that the time must be set. Set the
correct time. (Refer to“2. Setting the Time and Calendar”.)
Note: Normal time display will not be restored unless the time is set. (Refer to “Setting the Time
and Calendar”.)

61
[If the charge becomes insucient during normal time display]
If the charge becomes insucient, quickly charge the watch to restore normal
operations (normal time display).
When charging the watch by
subjecting it to light, the
second hand will move from
the STOP position to the SET
position.
Note: Continue to subject the watch to light until the second hand moves to the“SET”
position (approximately 30 minutes or more).
When the watch is
left without
charging
[Insucient charge warning]
The second hand points
to CHARGE.
[Stopped status]
The second hand
points to STOP.
[Time setting
warning display]
The second hand
points to SET.

62
<Low Power Warning>
Regardless what mode the watch is in, if the power becomes very low, the watch will switch
to the time display and the second hand will move to the ‘CHARGE’ position indicating that
recharging is necessary.
Aer the second hand has moved to the ‘CHARGE’ position, the watch will switch to display the
time in the following sequence, 24-hour hand, hour hand, minute hand, date (function hand).
Although the watch is functioning properly in this low charge state, it will stop within
approximately 11 days (approximately 2 days if the display switches from charge warning
operations to time change movement).
Restore the 1-second interval movement of the second hand by exposing the watch to light
sucient for charging.
If the watch stops due to insucient charge, be sure to fully charge
it, perform the all reset and 0-positioning procedure and then re-
set the time as well as the calendar.
Note, during low power:
• e chronograph will stop, even during measurement, and reset.
• e time set for local time (time dierence) is maintained.
• e alarm sound will not be emitted even if the alarm has been set.
• Crown (changing modes) and button operations will not
function.

63
<Time setting warning function>
As the watch is exposed to light sufficient for charging and begins re-charging after it has
stopped, the second hand will move to the “SET” position, informing you that the time is
incorrect and must be set.
Although movement of the 24-hour hand, hour hand, and minute hand will start after the
second hand has moved to the “SET” position, the time and calendar must be set aer the watch
has fully charged.
Note: When the time setting warning function is enabled.
• Crown and button operations other than those used to set the time and calendar will not function.
• e time setting warning function is cancelled when the crown is pulled out to position 2 (time
correction position) while in time/calendar mode. e second hand will stop at the SET position
unless the time is set aer pulling the crown out to position 2.
• If the watch has stopped due to an insucient charge, expose the
watch to light sucient for charging until the display switches to
the time setting warning indication (SET position) (30 minutes
or more).
<Overcharging prevention function>
Once the rechargeable cell is fully charged, an overcharging
prevention function will activate so that it is not charged any further.

64
<Power saving function>
If the watch is not exposed to light sufficient for charging and in the time/
calendar mode (TME) or local time mode (L-TM), the second hand will move
to the 0-position and stop, and the watch will enter power saving mode to
reduce power consumption.
Even though the second hand stops, the 24-hour hand, hour hand, and minute
hand will continue to keep the correct time. Also, the calendar will continue
to update according to the movement of the 24-hour hand, hour hand, and
minute hand.
• The Second Hand will start moving again once the watch is subjected to
light sucient for charging. However, if the watch is in insucient charge
warning mode, the second hand will stop at the CHARGE position. If the
watch is in time setting warning mode, the second hand will stop at the SET
position. If the watch is stopped, the second hand will stop at the STOP
position.
