A. Special functions of this watch
This is a full-scale divers watch with digital display
and an electronic depth gauge.
1) This watch measures and displays depth as soon
as you start diving, due to the water sensor
2) This watch measures the water temperature while
diving; and when not diving, the air temperature.
3) While you are diving, various log data is recorded.
4) After completing a dive, by using a communication
unit, you can transfer data to a personal computer
and also confirm the data with a personal computer
★ Compatible computers: IBM PC / AT or any other
compatible computer with keyboard and monitor.
(There are some computers that are not
compatible.) For more details, please read the
“Communications AQUALAND GRAPH USER’S
MANUAL”.
4) When the watch stops or something goes
wrong with it, please do not use it.
5) When the water depth meter
display on the watch shows a big
difference with other water depth
meters, please refrain from using
the watch.
(While Diving)
1) When the depth chart error warning function
operates – the dot display alternates between dot
display and “ERR” display as a warning.
2) When the battery warning function operates – the
dot display alternates between dot display and
“BAT.” (D201/D207)/“BT” (D202/D208) display, as
a warning. Once the battery warning display
appears, please realise we can”t guarantee the
accuracy of the depth measurement.
3) When the watch stops or something goes
wrong with it, please do not use it.
4) When the water depth meter has a big
difference with other water depth meters,
please do not use the watch.
D. For safe usage
[Make sure you read this caution]
CAUTION:
1. Items to check for safe usage
a. The depth display of this watch is up to 80m
(260ft). Although this watch has water resistance
up to 80m (260ft), for safe diving we recommend
that you stay shallower than 30 metres (100ft)
[sports diving].
b. The water depth meter in this watch is set
according to the sea water standard (1.025
gravity)
In case you use the watch in fresh water, i.e., you
need to make a conversion.
[Example]
When the watch is 80m (260ft) deep, in the case of
sea water it displays 80m (260ft), but when in fresh
water, it displays 78m (253ft); shallower than what it
really is.
c. Avoid descending too rapidly.
In order to get an accurate depth
reading, slow down the descent, or stop.
d. Avoid ascending too rapidly.
If you ascend at a speed greater than
1.5m (5ft) per 5 secs (D201/D207).
/0.9m (3ft) per 6 secs (D202/D208).
18m (60ft) per minute (D201/D207)
/9m (30ft) per minute (D202/D208)
according to the U.S. navy diving
manual, then the ascending speed
warning function will operate. The dot display
changes to “SLOW” display and an alarm will
sound.
Please maintain a safe ascending speed. Slow
down your ascent or stop in order to get an
accurate depth reading.
As rapid ascending is hazardous to the
human body, sometimes causing the bends,
always avoid it.
*The new regulation of the U.S. Navy diving manual
is executed in 1993, changing the Surface Speed
Warning at the rate of 9m/min. from 18m/min.
e. Do not use the watch in places where it is
exposed to large changes of air pressure or
temperature.
The watch will automatically check for unusual air
pressure, while in various normal modes (time
and calendar mode / surface mode / log mode /
alarm mode). If any abnormality is detected, the
dot display will alternate between dot display and
“ERR” display. When this happens, the water
depth cannot be measured. If the “ERR” display
disappears, the watch can be used normally.
✩When boarding a plane
When exposed to sudden pressure change
(pressurisation) as in the inside of an aeroplane, if
applicable, if the water sensor is touched with a
finger or moistened, the watch may change to
dive mode. If it changes to dive mode, dry the
water sensor, and cancel dive mode by holding
down button M for more than 2 seconds.
f. We recommend that you change the battery as
early as possible.
The life of the battery in this watch is about 3 years
after a new battery is installed. (Please look up S.
[Battery] for the conditions of usage). However,
the life of the battery changes a lot depending on
the frequency of use of various functions. In order
to enjoy safe diving, we recommend that you
change the battery ahead of time.
2. Things to check before diving
When you dive please check the following points.
a. Check your watch
1) Check that there are no
problems like scratches, cracks
or chips on the strap or glass.
2) Check that the band and
watch body are attached
correctly.
3) Check that the time and
calendar is set correctly.
4) Check if the dot display is
alternating between dot
display and “BAT.”
D201/D207)/“BT” (D202/D208) display. If so, then it
is time to change the battery.
➔ Consult various other warning functions for
counteraction needed.
5) Check that the dot display is not alternating
between dot display and “ERR”. If so then it
indicates that there has been unusual air
pressure detected.
➔ Consult various other warning functions for
counteraction needed
6) Check that the dot display is not alternating
between dot display and “CHEK” (D201/D207)
/“ERR” (D202/D208) display. If so, then you
should check the water sensor.
➔ Consult various other warning functions for
counteraction needed
7) Confirm the alarm sound by operating the alarm
monitor.
• Change to the alarm mode by pressing M button.
• Alarm monitor is activated while pressing A
button. At the same time the alarm will be switched
ON/OFF.
3. Points to notice while diving

environment.
b. Accurate water temperature is most likely to
indicate after 1 to 3 minutes from the start of your
dive.
c. When various warning functions are operating,
please heed the warning.
d. Be careful not to knock the watch against hard
objects like diving equipment or rocks, etc.
4. What to do after diving
a. Wash and rinse off any sea water, mud, sand,
and such present on the watch with fresh water.
Then dry any moisture completely, with a dry
cloth, etc.
b. Treat the sensor carefully. Do not remove the
cover or use sharp objects to clean dirt or dust
from it. If any dirt gets into the sensor, wash it
with clean water; if that doesn’t remove the dirt,
please take the watch to the nearest Citizen
Service Centre.
c. Do not expose the watch to chemicals.
d. For information about basic care for this watch,
please look at T. [for long usage].
E. Various warning functions
This watch has 5 warning functions to help you
avoid any trouble or danger while diving.
Use these warning functions, as much as
possible, as safety guidelines for diving. The
level of danger is often complex depending on
your body condition or diving situation, etc.
Even if there is no warning, it may not mean
there is no danger.

swimming diver when the watch is in diving mode.
2) The LED will flash once every 4 seconds to show
the watch is dive mode.
3) The water depth is measured and displayed
every second. The range of water depth
measurement is 1.0m~ 80.0m (4~260ft). When
the watch is deeper than 80.0m (260ft), it displays
“---m” and when shallower than 1.0m (4ft), it
displays “0.0m”; thus the watch informs you when
it is outside its depth measurement range.
4) The diving time display measures and displays in
1 second units up to 29 mins., 59 secs. When it
passes the 30 min. mark, the display changes to
units of 1 min. With a maximum measuring time
of 199 mins. After that, the watch starts from 0
secs, again.
5) The water temperature displays after 1 min. then

One dive: In this watch, one dive starts from the time
you dive deeper than 1m (4ft) to the time
you return shallower than 1m (4ft) depth.
However when diving deeper than 1m (4ft) after
being shallower than 1m (4ft) for less than 10 mins,
the watch will record it as one continuous dive.
• An example of 1 dive: (valid diving)
• Display examples of valid and invalid diving for this
watch
Cancelling diving mode
After Diving
1) If you stay shallower than 1m (4ft) (depth display
“0.0m”) for more than 10 mins, the diving mode
will be cancelled automatically. After cancellation,
the next mode will be different depending on the
following diving conditions.
• While valid diving............Changes to the surface

battery may require changing within 2 years after
purchasing the watch.
c. Changing the battery
1) When the battery is changed, the water
resistance should be checked, and if need be the
seals changed. So it should be carried out by the
manufacturer as a repair. Please arrange for a
Citizen Service Centre to look after your watch
through the shop you purchased it from.
2) When changing the battery, the log data and
profile data will be lost, so please transfer the
data to a personal computer or record it in a log
book beforehand.
3) If you leave a dead battery inside the watch,
leakage can cause damage, so we recommend
that you change the battery as soon as possible.
4) If you intend to use the watch overseas for any
length of time, there may be a chance you cannot
get the watch serviced, so we recommend you
change the battery prior to your departure.
5) The changing of the battery, and the checking
and changing of any incidentals, even within the
guarantee period, will be chargeable.
Please take care while using batteries:
• Battery replacement of this watch should be
carried out by the manufacturers in order to
maintain accuracy.
• When you store batteries (disused batteries, new
batteries) please keep them out of the reach of
children.
• In the event a child swallows a battery, take
him/her to a doctor immediately.
T. For long usage
1. Water-resistance
a. In order to ensure that your watch stays waterresistant, you should have it inspected once every
one or two years in addition to regular battery
replacement.
2. About the depth sensor (Pressure sensor)
a. There is a sensor cover that protects the
sensor area of your depth meter. Never remove it.
b. Be careful not to get any sand, particles, dust,
etc. on the sensor area. If this happens, rinse the
watch with alcohol or chemicals such as gasoline,
thinners, etc.
c. If you cannot adequately clean your watch,
please consult your nearest Citizen Service Centre.
3. Avoid Temperature extremes
Avoid leaving your watch in direct sunlight or in
extremely warm locations for long periods of time.
• This will cause malfunctioning and shorten the
life of the batteries.
Do not leave your watch for long periods of time
in extremely cold places.
• This may cause your watch to gain or lose time.
• Place your watch on your wrist to restore its
original accuracy should it begin to gain or lose time.
4. Avoid wet conditions
Do not operate your buttons when the watch is wet.
5. Avoid strong shock
This watch will withstand the bumps and jars
normally incurred while playing and during sport
activities.
Avoid dropping your watch on the ground or
otherwise imparting severe shock to it.
6. Avoid strong magnetic fields
Keep your watch out of the immediate vicinity of
strong magnets.
Generally, your watch is not affected by magnetic
fields from such household appliances as
television and stereos.
7. Avoid harmful chemicals, solvents and gases
Avoid wearing your watch in the presence of
strong chemicals, solvents and gases. If your
watch comes in contact with materials such as
gasoline, benzine, paint thinner, alcohol, spray
cosmetics, nail polish, nail polish remover,
adhesives or paint, discolouration, deterioration or
damage to the case, band, and the other
components may occur.
8. Polarising eyeglasses
The watch digital display can become difficult to
read clearly when wearing polarising eyeglasses
or sunglasses such as ski goggles and tinted
fishing glasses. This problem can be corrected by
turning your wrist slightly to change the angle
between the eye and watch, providing a clear
view of the display.
9. Keep your watch clean
Wipe off any moisture that adheres to the case,
glasses and band with a soft, clean cloth. Any dirt
left on the case or band may cause skin rash.
A watchband will easily become soiled with dust
and perspiration because it is in direct contact
with the skin. Even a stainless or gold band may
begin to corrode if it has not been cleaned for a
long period of time.
Mesh bands, because the meshes are very fine,
will lose their particular “flexibility” if they are left
soiled for a long time.
Metal bands should be washed periodically to
keep them looking beautiful at all times.
Metal watchbands are usually washed in mild,
soapy water and well wiped off with a soft,
absorbent cloth to make sure all water is
removed. Pay attention to prevent any water
from getting inside your watch when the band is
washed.
10. Periodic inspection
Getting your watch checked once every year or
two is recommended to ensure long use and
trouble-free operation.
11. Be sure to keep the batteries out of reach of
infants and small children. Should accidental
ingestion occur, consult a doctor at once.
