Cal. E81*
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 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 1/20 second units up to 59 minutes, 59.95
seconds.
2. Before Using
A secondary battery is used in this watch to store
electrical energy. This secondary 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).
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.
Proper Use Of This Watch
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 every day.
3. Names of Components
4. Functions Unique to Solar-Powered Watches
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 five days have elapsed (roughly two
days in the case of 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 the 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.
• Set the 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.
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 cancelled. 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.
Overcharging Prevention Feature
The overcharging prevention feature
is activated when the secondary
battery is fully charged so that it is not
charged further.
Power Save Feature
When the power save feature 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 the minute hand.
• During normal hand movement, when the power
generation is resumed after the second hand stops
at the 0 seconds position, the second hand is
rapidly advanced to the current 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 secondary 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.
5. General Reference for Charging Times
The time required for recharging varies according to
the model of the watch (colour of the dial, etc.). The
following times are shown below to serve only as a
reference.
*Recharging time refers to the amount of time the
watch is continuously exposed to light.
6. Notes Regarding Handling of this Watch
Try to keep the watch charged at all times
Please note that if you wear long sleeves, the watch
can easily be insufficiently charged as a result of it
being concealed and unable to be exposed to light.
• When you take the watch off, try to place it in as
bright a location as possible to ensure that it
always keeps the correct time.
CAUTION Charging Precautions
• Avoid recharging at high temperatures (over about
60˚C/140˚F) since this may result in damage to the
watch during recharging.
Examples: Charging the watch in close proximity to
an incandescent lamp, halogen lamp or
other light source that can easily reach
high temperatures, charging the watch in
a location that reaches high temperatures
such as on a car dashboard.
• When charging the watch with an incandescent
lamp, always make sure the watch is at least 50cm
(20in.) away from the lamp so that it does not reach
excessively high temperatures during charging.
7. Replacing the Secondary Battery
Unlike ordinary batteries, the secondary battery
used in this watch does not have to be periodically
replaced since it is unable to be charged and
discharged repeatedly.
8. Switching the Mode (Display Function)
This watch is equipped with four modes consisting
of time/calendar, chronograph, local time and alarm.
Since the mode changes when the crown is turned,
the current mode can be confirmed with the mode
hand.
9. Hand 0-Position Check and Correction
Before using this watch, check that the functions of
the watch operate properly by performing the
following procedure.
0-Position: This refers to the base position of each
hand that enables the watch to function properly.
[0-Position Check]
1. Turn the crown to switch the watch to the
chronograph [CHR] mode.
2. Pull the crown out to position 1 to check the 0position (function hand and date wheel correction
mode). Confirm that the 24-hour hand, hour hand,
minute hand, second hand and function hand
rapidly advance to the 0 position, and the date
wheel displays “1”.
0 positions of each Hand (Base Positions):
24-hour hand: 24:00
Hour hand, minute hand: 00:00
Second hand: 00 seconds
Function hand: 0 position
(12:00 position)
Date wheel: 1st
Perform the “0-Position
correction” when the hands and
date wheel are not at the positions indicated above.
[0-Position Correction]
0-Position Correction of Function Hand and
Date Wheel:
1. Pull the crown out to Position 1 in the
chronograph [CHR] mode to correct the function
hand and date wheel.
2. Click (turn) the crown to the left to align the date
wheel.
(1) Clicking the crown once causes the function
hand to make four revolutions and the date to
be corrected by one day.
(2) Turning the crown rapidly (clicking continuously
two or more times) causes the function hand
to advance continuously. When stopping the
function hand, click the crown once to the
right or left. When the function hand is not
stopped manually, it stops automatically after
advancing 31 days.
The 12:00 position immediately after the date
changes to the “1st” is the 0-position of the
function hand. After correcting the date wheel to
the “31st” by turning the crown, press button (A)
to finely correct the function hand so that the
function hand is aligned at the 0 position after the
date wheel changes to the “1st”.
0-Position Correction of 24 Hour Hand, Hour
Hand, Minute Hand and Second Hand:
1. Pull the crown out to Position 2 in the
chronograph [CHR] mode to correct each hand.
2. Pressing button (A) causes the second hand to
be corrected by one second at a time each time it
is pressed. Continuously pressing button (A)
causes the second hand to advance rapidly.
3. Clicking the crown allows correction of the 24 hour
hand, hour hand and minute hand.
(1) Clicking the crown once to the right causes
the hour and minute hands to move clockwise.
(2) Clicking the crown once to the left causes the
hour and minute hands to move counterclockwise.
• Turning the crown rapidly (clicking continuously
two or more times) causes the hands to advance
rapidly. When stopping the hands, click the
crown once to the right or left. When the hands
are not stopped manually, they stop automatically
after being corrected by 12 hours.
10. Setting the Time and Date
[Setting the Time]
1. Turn the crown and align the mode hand at the
time/calendar [TME] mode.
2. When the crown is pulled out to Position 2 (time
setting position), the second hand rapidly
advances to the 0 position and stops.
Note: When the second hand does not stop at
the 0 seconds position, reset the base
position in the “0-Position Correction Mode”.
Note: If the crown is pulled out to Position 2
when the date is changing, the date wheel
and function hand stop at that time, and
are then advanced by the remaining
amount after the second hand is rapidly
advanced to the 0 seconds position.
3. Click (turn) the crown to set the time.
(1) Clicking the crown once to the right causes
the 24-hour hand, hour hand and minute hand
to move in the clockwise direction.
(2) Clicking the crown once to the left causes the
24-hour hand, hour hand and minute hand to
move in a counter-clockwise direction.
• Turning the crown rapidly (clicking continuously
two or more times) causes the hands to advance
rapidly. When stopping the hands, click the
crown once to the left or right. When the hands
are not stopped manually, they stop
automatically after being corrected by 12 hours.
4. Return the crown to the normal position in
synchronisation with a telephone time signal or
other time service.
5. Pressing button (B) allows correction of the
month. Press button (B) and align the second
hand at the position corresponding to the month.
[Setting the Date]
The calendar function of this watch is a full-auto
calendar that changes the year, month and date
automatically, including leap years.
6. Return the crown to the normal position after setting
the date. The watch will resume keeping time once
the second hand catches to the current seconds.
1. Turn the crown to switch the watch to the time/
calendar [TME] mode.
2. When the crown is pulled out to Position 1 (date
correction position), the second hand rapidly
advances to the month display position stored in the
memory, while the function hand moves to the year
display position (number of years elapsed since
the most recent leap year), after which both stop.
Note: If the crown is pulled out to Position 1 when
the date is changing, the second hand
advances rapidly after the date changes.
3. Click (turn) the crown to the left to set the date.
• Clicking the crown once to the left causes the
function hand to make four revolutions and the
date to be corrected by one day.
• Turning the crown rapidly (continuously clicking
two or more times) causes the hand to advance
continuously. When stopping the hand, click the
crown once to the right or left. When the hand is
stopped manually, it stops automatically after
being advanced 31 days.
4. Pressing button (A) allows correction of the year
(number of years elapsed since the most recent
leap year).
Press button (A) and align the function hand at
the position corresponding to the year (number of
years elapsed since the most recent leap year).
*Interpretation of Year/Position of Function Hand*
Leap year:
0 min position
1 year after most recent leap year: 6 min position
2 years after most recent leap year: 12 min position
3 years after most recent leap year: 18 min position
<When the calendar has been set to a
non-existent date>
When the crown is returned to the normal position
from the date correction mode, the watch switches
to the first day of the following month.
Example: February 29, 30 or 31 in an ordinary year
->March 1
February 30 or 31 in a leap year
->March 1
11. Using the Chronograph
The chronograph is able to measure time up to a
maximum of 59 minutes, 59.95 seconds in 1/20th
second units, after which resets to 0 seconds.
[Explanation of Hands During Chronograph
Measurement]
When the crown is turned and the mode hand is set
to the chronograph [CHR] mode, the second hand
and function hand are rapidly advanced to the 0
position and the watch enters the chronograph mode.
• Second hand:
Switches to the chronograph second hand. The
second hand advances rapidly and makes one
revolution only when starting at 0 seconds, after
which it moves in 1 second increments to measure
chronograph seconds.
• Function hand:
Switches to either chronograph minutes or
chronograph 1/20th seconds. The function hand
moves in one minute increments to measure
chronograph minutes. When button (B) is pressed
when the chronograph is stopped, the function
hand switches to 1/20th seconds display during
time button (B) is pressed.
Note: 24 hour hand, hour hand, minute hand, date
wheel:
• Continue to display the current time when the watch
has been switched from the time/calendar mode.
• Continues to display local time when the watch
has been switched from the local time mode.
• Continues to display the alarm set time when the
watch has been switched from the alarm mode.
[Chronograph Measurement]
1. Turn the crown to set the mode hand to the
chronograph [CHR] mode.
2. Press button (A) to start and stop the chronograph.
A confirmation tone is heard whenever button (A)
is pressed.
3. Continuously pressing button (A) when the
chronograph is stopped causes the chronograph
second hand and chronograph minute hand to be
reset to the 0 position.
12. Setting Local Time
The local time function allows the time in a different
time zone to be set separately from the current time.
Local time is set by performing a time difference
correction in 1 hour units based on the current time
(time of the time mode/TME). The minute and second
hands move in co-ordination with the current time.
[Time Difference Correction Procedure]
1. Turn the crown to set the
mode hand to the local time
[L-TM] mode.
2. Pull out the crown to Position
2 (local time setting position).
3. Click the crown to the right or
left to correct the time
difference.
• When the crown is clicked to the right, the hour
hand moves by 1 hour in the clockwise direction.
• When the crown is clicked to the left, the hour hand
moves by 1 hour in the counter-clockwise direction.
Note: The hour hand is not advanced rapidly even if
the crown is continuously clicked two or more
times. Perform correction accurately 1 hour at
a time. Furthermore, the range of time
difference correction is 23 hours based on
the current time.
4. Always make sure to return the crown to the
normal position after correcting the time
difference.
Note: If the hour hand passes 12:00 AM (midnight)
during correction, the date is advanced by one
day following the completion of hand movement.
If the time difference is corrected in the
counter-clockwise direction and the hour hand
passes back over 12:00 AM, although the
date is corrected following completion of hand
movement, since the date is corrected by 30
days in the clockwise direction, it takes about
2-3 minutes for the date to be corrected. Pay
attention to AM and PM when correcting time
difference.
Note: When returning the time difference to the
original setting, return the hour hand in the
direction opposite that when the time
difference was corrected.
13. Using the Alarm
The alarm function uses a 24-hour clock. Once the
alarm has been set, the alarm sounds for 15 seconds
when the time is reached once a day. The time at
which the alarm sounds applies to the time (TME)
mode, and cannot be set based on the local time (LTM).
[Setting the Alarm Time]
1. Turn the crown and set the
mode hand to the alarm
[ALM] mode.
• Second hand: Moves rapidly
to the ON or OFF position
• 24 hour hand, hour hand,
minute hand: Move the previously set alarm time.
• Function hand: Stops at the 0 position.
2. Pull out the crown to position 2 (alarm setting
position).
• The alarm setting is turned ON automatically.
3. Click (turn) the crown to set the alarm time.
(1) Clicking once to the right causes the hour and
minute hands to move clockwise.
(2) Clicking once to the left causes the hour and
minute hands to move counter-clockwise.
• Turning the crown rapidly (continuously
clicking two or more times) causes the hands
to advance rapidly. When stopping the hands,
click the crown once to the right or left. When
the hands are not stopped manually, they stop
automatically after being corrected by 12 hours.
• Set the alarm while making sure not to mistake
AM and PM by referring to the 24 hour hand.
4. Return the crown to the normal position after
setting the alarm time.
[Switching Alarm ON and OFF]
The alarm is switched ON and OFF each time
button (A) is pressed when the crown is pulled out
to Position 1 or Position 2 in the alarm mode.
[Alarm Tone Monitor]
When button (A) is pressed with the crown in the
normal position in the alarm mode, the alarm tone
sounds for as long as button (A) is pressed.
[Stopping the Alarm Tone]
Press either button (A) or (B) to stop the alarm tone
while it is sounding.
14. All-Reset
This watch may not function properly as a result of
being subjected to the effects of static electricity or
strong impact and so forth. When this happens, set the
hands of the watch to their respective base positions
according to the following procedure after performing
the all-reset procedure.
When performing the all-reset procedure, first make
sure that the watch is fully charged and the second
hand is moving in one second increments. If the allreset procedure is performed when the watch is
insufficiently charged, it may not function properly or
remain stopped following the all-reset procedure.
1. Turn the crown to set the mode hand and the
chronograph [CHR] mode.
2. Pull out the crown to Position 2 (0 position correction
mode).
• Each of the hands and date wheel move to their
respective 0 positions stored in the memory and
then stop.
3. Press buttons (A) and (B) simultaneously and then
release.
• Following a confirmation tone, each of the hands
perform a demonstration movement in the order of
the function hand, 24 hour hand, hour hand, minute
hand and second hand to indicate that the all-reset
procedure is finished.
Note: Following the all-reset procedure, make sure to
properly reset each mode after performing 0position correction for each hand before using
the watch. The watch will remain stopped and
not run unless 0-position correction is performed.
15. Precautions
For correct use within the design limits of the watch, confirm the level of water
resistance of your watch, as indicated on the dial and case, and consult the table.
• Water-resistance for daily use (to 3 atmospheres):
This type of watch is water-resistant to minor
exposure to water. For example, you may wear the
watch while washing your face; however it is not
designed for use underwater.
• Upgraded water resistance for daily use (to 5
atmospheres): This type of watch is water-resistant
to moderate exposure to water. You may wear the
watch while swimming; however, it is not designed
for use while skin diving.
• Upgraded water-resistance for daily use (to 10/20
atmospheres): This type of watch may be used for
skin diving; however, it is not designed for scuba
or saturated diving using helium gas.
CAUTION
• Be sure to use the watch with the crown pressed
in (normal position). If your watch has a screw-type
crown, be sure to tighten the crown completely.
• Do NOT operate the crown or button with wet
fingers or when the watch is wet. Water may enter
the watch and compromise water-resistance.
• If the watch is used in seawater, rinse with fresh
water afterward and wipe with a dry cloth.
• If moisture has entered the watch, or if the inside
of the crystal is fogged up and does not become
clear within a day, immediately take the watch to
your dealer or Citizen Service Centre for repair.
Leaving the watch in such a state will allow
corrosion to form inside.
• If seawater enters the watch, place the watch in a
box or plastic bag and immediately take it in for
repair. Otherwise, pressure inside will increase, and
parts (crystal, crown, buttons, etc.) may come off.
CAUTION: Keep your watch clean.
• Leaving dust and dirt deposited between the case
and crown may result in difficulty in pulling the
crown out. Rotate the crown while in its normal
position, from time to time, to loosen dust and dirt
and then brush it off.
• Dust and dirt tend to be deposited in gaps in the
block of the case or band. Deposited dust and dirt
may cause corrosion and soil your clothing. Clean
the watch occasionally.
Cleaning the Watch
• Use a soft cloth to wipe off dirt, perspiration and
water from the case and crystal.
• Use a soft dry cloth to wipe off perspiration and dirt
from the leather band.
• To clean a metal, plastic or rubber watchband,
wash away dirt with mild soap and water. Use a
soft brush to remove dust and dirt jammed in the
gaps in the metal band. If your watch is not waterresistant, take it to your dealer.
Note: Avoid using solvents (thinner, benzine, etc.),
as they may mar the finish.
CAUTION: Operating Environment
• Use the watch within the operating-temperature
range specified in the instruction manual.
Using the watch where temperatures are outside
the specified range, may result in deterioration of
functions or even stoppage of the watch.
• Do NOT use the watch in places where it is
exposed to high temperature, such as in a sauna.
Doing so may result in a skin burn.
• Do NOT leave the watch in a place where it is
exposed to high temperature, such as the glove
compartment or dashboard of a car.
Doing so may result in deterioration of the watch,
such as deformation of plastic parts.
• Do NOT place the watch close to a magnet.
Timekeeping will become inaccurate if you place
the watch close to magnetic health equipment
such as magnetic necklace or a magnetic latch of
a refrigerator door or handbag clasp or the
earphone of a mobile phone. If this has occurred,
move the watch away from the magnet and reset
the time.
• Do NOT place the watch close to household
appliances that generate static electricity.
Timekeeping may become inaccurate if the watch
is exposed to strong static electricity, such as is
emitted from a TV screen.
• Do NOT subject the watch to a strong shock such
as dropping it onto a hard floor.
• Avoid using the watch in an environment where it
may be exposed to chemicals or corrosive gases.
If solvents, such as thinner and benzine, or
substances containing such solvents come in
contact with the watch, discolouration, melting,
cracking, etc., may result. If the watch comes in
contact with mercury used in thermometers, the
case, band or other parts may become
discoloured.
