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 perpetual calendar that changes
the year, month and day automatically through February 28, 2100, including leap
years, a time difference correction function that makes it possible to easily
change the time difference without stopping the watch, and a power save
function that reduces current consumption when the solar cell is not exposed to
light.
2. BEFORE USING
This watch is a solar powered watch. Be sure to fully charge it prior to
use and setting
This watch is a solar-powered watch. Make sure to charge the watch prior to use
by adequately exposing it to light. If the watch should happen to stop as a
result of being insufficiently charged, charge by exposing the watch to intense
light such as direct sunlight.
An Eco Drive rechargeable battery (manganese titanium) is used in this watch to
store electrical energy. This Eco Drive Rechargeable battery is a clean energy
battery that does not contain mercury or other toxic substances. Once fully
charged, the watch circuit will continue to keep time for about 2 years without
additional charging (when the power save function is operating).
<Proper Use of this Watch>
To use this watch comfortably, make sure to recharge it before it stops running
completely. There is no risk of overcharging no matter how much the watch is
charged (Overcharging Prevention Function). It is recommended that the watch be
recharged everyday.

memory and then stops
2. Turn the crown and set the date
a. Turn the crown to the right to set the second hand to the position
corresponding to the year (number of years elapsed since the most
recent leap year) and month. Turning the crown continuously causes the
second hand to advance rapidly.
Examples
! In the case of December in a leap year: Align the second hand at ‘0’
seconds.
! In the case of April in a year that is three years after the most
recent leap year: Align the second had as 23 seconds (between 4:00
and 5:00)
B. The date is advanced by one day if the crown is turned to the left.
Turning the crown continuously causes the date to be advanced
continuously. Turn the crown to either the left or right to stop the
date from rapidly advancing.
3. Always make sure to return the crown to the normal position next to the case
after setting the date. The second hand advances to the current second and
the hands begin to move normally.

<When Setting the Date by Continuously Turning the Crown>
The date can be set easily by stopping advancing the date rapidly two to three
days before the correct date and then advancing the date one day at a time.
<When the Date has been set to a date that does not exist>
The date automatically changes to the first day of the following month when the
crown is returned to the normal position from the date correction state.
Examples:
Normal Years:
•
March 1 when the date has been set to February 29.30 or 31
October 1 when the date has been set to September 31
Leap Years
•
March 1 when the date has been set to February 30 or 31
October 1 when the date has been set to September 31
Correcting the Time Difference
When button (A) is pressed and the crown is turned continuously, time difference
can be corrected in 1 hour increments. Time difference cannot be corrected
continuously.
The time difference can be corrected for 30 seconds after button (A) has been
pressed or for 30 seconds after time difference correction (after the hands
finish moving)
1. Put the crown in the normal position.
2. When button A is pressed, the second hand performs a demonstration movement
(forward rotation -> backward rotation -> forward rotation).
3. Correct the time difference by turning the crown to the right or left.
1. When the crown is turned to the right, the hour hand moves forward by one
hour (clockwise rotation).
2. When the crown is turned to the left, the hour hand moves backward (counterclockwise-rotation) by one hour.
Note 1: If the time difference is corrected in the forward direction, the date
after the hands are finished moving is corrected by +1 day when the hour and
minute hands pass 12:00 AM. Pay attention to AM and PM when correcting the
time difference.
Note 2: When returning the time difference to its original setting, return the
hour hand in the opposite direction in which it was corrected. If the time
difference is corrected in the backward direction, the date after the hands
are finished moving is corrected by –1 day when the hour and minute hands pass
12:00 AM. This takes about two minutes, however, since the date is corrected
in the forward direction.

time) is 10:OO AM:
The time difference between Tokyo and London is -9 hours. Since it is 1:00 AM in
London when it is 10:00 AM in Tokyo, in the case of correcting the time
difference at this time:
1. Press button A.
2. Turn the crown to the left to turn the hands backward (counter-clockwise) by 9
hours.
Note:
If the crown is turned to the right to move the hands clockwise to set the
time to 1:00, the time will be 1:OOPM and the calendar function will not
operate correctly, preventing the date from changing at the proper time.

5. FUNCTIONS UNIQUE TO SOLAR-POWERED WATCHES
When the watch becomes insufficiently charged, the following warning functions
are activated to inform the wearer that the watch is insufficiently charged.
Note 1
Irregular two-second-interval movement will continue if the time is not reset
Note 2
Check the date since it also may not be correct
Return to Table of Contents
Return to Table of Contents
Insufficient Charging Warning Function
The second hand moves at two-second
intervals to indicate that the watch is
insufficiently charged. Although the watch
will continue to operate normally at this
time as well, it will stop after about 2
days have elapsed since the start of twosecond-interval movement. Expose the watch
to light to return the second hand to onesecond interval movement.
Time Setting Warning Function
When the watch is again exposed to light
after stopping, although the second hand
begins to move, since the time is incorrect,
the second hand moves irregularly at twosecond intervals to indicate that the time
is incorrect. Reset the time after the watch
has been sufficiently charged. The second
hand will continue to move irregularly at
two-second intervals unless the time is
reset.
Overcharging Prevention Function
The overcharging prevention function is activated when the Eco Drive
Rechargeable battery is fully charged so that it is not charged further.
Power Save 1
When power is no longer generated as a result of light not shining on the
solar cell continuously the second hand stops and the watch enters Power Save
1 to reduce power consumption of the rechargeable battery. The minute and hour
hands continue to keep time even though the second hand is stopped.
Furthermore, operation of the calendar is linked with the movement of the hour
and minute hands
<Power Save 2>
When the Power Save 1 state continues for about 3 days, the watch
automatically switches to the Power Save 2 state and movement of the hour and
minute hands as well as the calendar operation stop to further reduce power
consumption of the rechargeable battery.
Note: The power save function is not activated even when power is not
generated as a result of light not shining on the solar cell during the
time the Eco Drive Rechargeable battery is fully charged and the
overcharging prevention function is activated.
Canceling Power Save
The power save function is canceled when the solar cell is exposed to light and
power generation is resumed. The of the hands advance rapidly to the current
time and begin moving.

7.NOTES REGARDING USE OF THIS WATCH
<Try to keep the watch charged at all times. >
Please note that if you frequently wear long sleeves, the watch can easily become
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 dam- age 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 50 cm (20 in.) away from the lamp so that it does not
reach excessively high temperatures during charging.

9. ALL-RESET
The display of this watch may not read correctly as a result of being subjected
to the effects of static electricity or strong impact and so forth. When this
happens, perform the procedure described in section "10. REFERENCE POSITION
ALIGNMENT" after performing the all-reset procedure described below.
1. Pull out the crown to the second click (time setting position).
• The second hand moves to the 0-position stored in memory and stops.
2. Continuously press button (A) for at least 1 second.
• The hour and minute hands perform a demonstration movement (forward
movement backward movement ---> forward movement).
• The second hand makes one complete revolution in the clockwise direction
• This completes the all-reset procedure. Always make sure to perform the
reference position alignment procedure after performing all-reset.
Note 1: Demonstration movement is not performed when the watch is
insufficiently charged. Perform the all-reset procedure only after charging the
watch sufficiently.
Note 2: Do not perform the all reset procedure while the date is changing. This
can cause the date position to shift. If the date position should happen to
become out of position, pull out the crown to the first click after completing
the all-reset procedure and the crown to the left while pressing button (A) to
set the date to the correct position.
10. REFERENCE POSITION ALIGNMENT
After performing the all-reset procedure, align the hour and minute hands at
their reference positions by pulling out the crown to the second click, and the
second hand and date to their reference positions by pulling out the crown to the
first click.
1. Align the Hour and minute hands at the 12:00 position with the crown pulled
out to the second click.
• Turning the crown to the right moves the Hour and minute hands forward.
• Turning the crown to the left moves the Hour and minute hands backward.
• Turning the crown continuously causes the hands to advance rapidly. Turn
the crown to the left or right to stop the hands from advancing rapidly.
2. Align the second hand at the 12:00 position with the crown pulled out to the
first click. In addition, align the date at ‘1’.
• Turning the crown to the right moves the second hand to move forward 1
second.
• Turning the crown to the left moves the date to move one day forward.
• Turning the crown continuously to the left caused the date to advance
continuously. Turn the crown to the Turn the crown to the left or right to
stop the hands from advancing rapidly.
3. Once each hand has been aligned at the 12:00 position and the date has been
aligned to ‘1’, return the crown to the closed position next to the case.
NOTE 1: It takes about 1 second for the watch to store the reference position
in memory. Once the reference position has been stored in memory, the second
hand will begin irregular two-second-interval movement. The reference
position may not be stored in memory if the crown is operated before the
start of the irregular two-second-interval movement after the returning the
crown to the normal position.
NOTE 2: The second hand will continue to remain stopped even if the crown is
returned to the normal position unless the reference position alignment
procedure is performed.
4. After performing the reference position alignment procedure, properly reset
the time and date.
The watch shows 12:00 AM after reference position alignment has been
performed. Set the time and date by referring to section “4. SETTING THE TIME
AND DATE” while paying attention to the AM and PM.

PRECAUTIONS ABOUT CARE AND
HANDLING OF WATCHES
TEMPERATURE CARE
Avoid temperature extremes. Exposing your watch to high
temperatures, such as placing it on the dashboard of a vehicle
or use in a hot tub, may cause the watch to malfunction,
shorten battery life or damage certain components. Leaving
the watch in extreme cold temperatures may cause irregular
timekeeping until the watch returns to normal operating
temperature.
SHOCK-RESISTANT
The watch may be worn while playing golf or other activities,
but avoid severe shocks such as dropping it on a hard surface.
MAGNETIC-RESISTANT
No problem should occur from using the watch around
ordinary household electric appliances such as TV sets or
stereos. Keep away from magnets.
CHEMICAL/GAS RESISTANT
Do not expose the watch to chemicals or gases for long
periods.
WATCH CLEANING
Stains, waterspots and accumulated dirt on the case, crystal
or band should be removed with a soft cloth to prevent
damage and premature wear.
HANDLING OF WATER-RESISTANT WATCHES
Although water-resistant watches are warranted, steps should
be taken to avoid damage that may result from
accidents or mishandling:
■ Do not operate the crown or push-button in the water or
while the watch is wet. Tighten screw lock crown completely.
■ Should the watch become immersed in water, dry it off
right away. If the watch comes in contact with salt water, be
sure to rinse it thoroughly in warm fresh water to remove any
trace of salt.
■ If a watch is wet from cleaning or by accident, never store it
in a closed container. It should be dried immediately or taken
to a watchmaker or jeweler if moisture is inside the case to
prevent damage from rust.
■ Vital components necessary to resist the entrance of
moisture deteriorate with time and use. Gaskets, crowns and
other materials should be replaced every year or two to ensure
Marking
on the Dial
Marking
on the
Caseback
that water resistant quality remains at factory specifications.
CARE FOR METAL BRACELETS
To extend the life and maintain the good appearance of the
metal watch bracelet, the following recommendations are
given:
■ Be aware that since the watch and bracelet is worn next to
the skin, it collects dust and perspiration and becomes soiled if
not cleaned regularly. This is particularly true of the inner parts
of the links or mesh of the bracelet.
■ Soil and rust, when present in a bracelet, are dissolved by
perspiration and can cause staining of cuffs and
irritation of the skin in some instances.
■ Heavy perspiration should be wiped off the watch and
bracelet with a soft dry cloth. The bracelet should be cleaned
occasionally by using an old toothbrush and warm soapy
water after which the soap is thoroughly rinsed with clear water
and the bracelet dried completely. The foregoing manner of
cleaning should not be done if the watch is not water-resistant
but should instead be done by your jeweler.
CARE FOR STRAPS
LEATHER
■ Heavy perspiration, if not removed from a leather strap, can
wash out the natural oils and cause the leather to become dry
and deteriorate. Any moisture should be blotted with a soft dry
cloth or paper towel and the strap allowed to dry naturally.
■ Salt residue and soil can be removed from the leather by
cleaning with a dampened soft cloth and mild soap or saddle
soap.
■ Occasionally, the inside surface of the strap should be
cleaned by using a soft cloth dampened with alcohol.
■ The strap should always be worn a little loosely (one finger
space between wrist and strap) to allow air to circulate thus
causing any moisture to evaporate.
RUBBER
■ Rubber straps should be washed frequently with mild soap
and warm water using a soft brush.
■ Thorough cleaning, using the same method, should
especially be done after use in salt water.
■ Solvents, oils, perspiration, tanning lotion and salt can cause
rubber to deteriorate if not removed.

Return to Table of Contents
Water Resistance
The water-resistant quality of our timepieces is offered in varying degrees depending on the model. This
ranges from non-water resistant models to those suitable for SCUBA diving. Water resistance of our
timepieces is measured in BAR or Barometric Pressure. Each BAR of pressure is equal to 14.5 pounds per
square inch of pressure.
Water resistance is measured when the watch is at a static, or motionless state. As the watch is moved in
water, such as from the motion of swimming, pressure is added from velocity. While you may be swimming in
a pool at surface level, the watch may be experiencing forces equal to that of 100 feet of water pressure
(3 BAR). Diving into a pool can cause forces on the watch to exceed those pressures. As such, you
should always allow a margin of safety when exposing your watch to moisture. Never "push the limit" of
the degree of water resistance of your timepiece.
A primary factor to keep in mind about water resistance is that periodic maintenance is needed to
maintain original factory specifications for water resistance. When a watch is new, it meets
specifications for water resistance as indicated on the case back. However, as the watch ages, the
gaskets that seal the watch become dry and brittle, diminishing its water resistant quality. Exposure to
environments such as chlorinated pools, salt water or soaps from showering can accelerate drying of the
gaskets. We recommend that the gaskets be changed at least every 18 to 24 months to maintain the water
resistant quality of your timepiece. If the watch is frequently exposed to chlorinated pools, soaps salt
water, etc., we recommend that the gaskets be changed on a yearly basis.
From time to time, you may notice condensation that appears then goes away after a short period of time.
This is a normal occurrence and happens primarily from sudden temperature changes. When there are sudden
temperature changes such as entering a cool building from the hot out of doors, or jumping into pool on a
hot day the watch may fog. Conversely, if you go to the cold outdoors from a warm building, fogging may
occur. As long as the fogging clears in a short period of time, there is no need for concern.
Be sure the crown is completely pushed in prior to any contact with moisture. If your model is equipped
with a screw down crown, be sure it is properly seated against the case. Do not operate the crown or any
push button when the watch is wet as this may allow the entrance of moisture. . If at anytime, you notice
moisture in your timepiece that does not clear in a short period of time, you should send your timepiece
as soon as possible to the nearest Authorized Service Center for inspection.
You can determine the level of water resistance of our watches from the markings on your case-back.
Additionally, models that are water resistant to 100 or 200 meters have an indication on the dial as
well. The case-backs and dials are normally marked as follows:
The case back has no indication of water resistance
This indicates the watch is a non water-resistant model and is not designed for contact with moisture at
all. Caution should be exercised to avoid any contact with moisture, such as when washing your hands or
from a rainstorm.
“Water Resist”
This watch is designed to withstand water from accidental splashing, such as from washing your hands or
rain. Any submersion into water may result in the entrance of moisture.
“Water Resist 10BAR” or “W.R. 10BAR”, Dial marked “WR100”
This watch is designed to withstand water pressure up to 333 feet. This includes water exposure from
accidental splashing and rain, but also from showering, swimming in a pool and snorkeling. Be sure to
rinse the watch with fresh water after exposure to a chlorinated pool, salt water, soaps, etc. After
rinsing with fresh water, be sure to dry the exterior with a soft cloth.
“Water Resist 20BAR” or “W.R. 20BAR”, Dial marked “WR200”
This watch is designed to withstand water pressure up to 666 feet. This includes all exposure to water up
to and including recreational SCUBA diving. Be sure to rinse the watch with fresh water after exposure to
a chlorinated pool, salt water, soaps, etc. After rinsing with fresh water, be sure to dry the exterior
with a soft cloth.
Special Note about Jacuzzis and Hot Tubs
The various components used in the manufacture and assembly of your watch expand at various rates. This
results in a loss of the sealing capabilities of gaskets, which may allow moisture to enter. In addition,
heat from these sources can cause deformation of certain materials leading to mechanical failures. For
these reasons, you should remove your watch before entering a hot tub or Jacuzzi.
