- General Diving Precautions -
- Precautions Relating to Use of this
Watch -
WARNING
• In the case of using this watch for diving, always
make sure to receiving the proper diving training
from a licensed instructor to acquire the
experience and skills required for safe diving.
• Make sure you have completely mastered the
handling and operation of this watch. Even
recreational diving can be potentially dangerous.
Diving without the proper or adequate training can
lead to a fatal or serious accident.
WARNING
Each diver should take responsibility for planning
and executing his or her own diving plan to ensure
safe diving. This watch is not equipped with a
function that prevents decompression sickness. In
addition, this watch is also unable to check differences
in physiological functions of individual divers or
differences in physical condition on that day. Since the
occurrence of decompression sickness is greatly
affected by physical condition, the degree of the risk of
decompression sickness varies depending on your
physical condition on that day. It is recommended to
avoid diving whenever you are in poor physical
condition such as when you are ill, fatigued, have not
had enough sleep or have a hangover.
8
DANGER
• This watch is not equipped with a function that
indicates decompression diving. Do not engage in
decompression diving while using this watch.
• This watch is not compatible with Nitrox diving.
Never use this watch for Nitrox diving.
DANGER
Do not lend the watch or share the watch with
another person while resting on the surface (during
operation of the surface mode). In addition, the data
displayed on the watch should never be used as the
data for another diver. This watch is designed on the
premise of personal use. Since data accumulated
during the previous time is continued to be used while
in the surface mode, the use of the watch by another
person will prevent data from being calculated that is
suitable for that person and can lead to the risk of a
fatal or serious accident.
DANGER
Avoid flying in an airplane when the surface mode
is operating. Flying in an airplane without allowing
an adequate amount of time for resting following
diving can result in the risk of decompression sickness.
It is recommended to avoid flying for at least 24 hours
following the completion of diving whenever possible.
There is no method for completely preventing
decompression sickness caused by flying in an airplane
after diving.
9
WARNING
In the case of using this watch for diving, always
make sure to use the watch in combination with
other diving instruments (dive table, divers' watch,
residual pressure gauge or water depth gauge).
Sudden atmospheric fluctuations and changes in water
temperature may have an effect on the display and
performance of the watch. In addition, always make
sure to use the watch in combination with other diving
instruments in case the watch should happen to
malfunction.
WARNING
Always make sure to inspect all functions of the
watch before each dive to prevent malfunctions and
accidents caused by the use of improper settings. In
particular, make sure to check whether the watch is
sufficiently charged and that there are no warnings
displayed on the display.
WARNING
The use of this watch for diving is limited to
recreational diving (non-decompression diving) at a
water temperature of 0˚C to +40˚C (32˚F to 104˚F).
Do not use this watch for the following types of diving:
• Diving outside the above temperature range
• Decompression diving
• Saturation diving using helium gas
• High-altitude diving at 3,000 m (10,000 ft) above
sea level or higher
• Diving in water other than saltwater (water having a
specific gravity of 1.025)
WARNING
Allow a sufficient margin during diving with respect
to the no-decompression diving limit time.
10
11
WARNING
In the case you happen to engage in decompression
diving, immediately begin ascending to the surface
while observing an ascent rate of no more than 9 m
(30 ft)/minute according to a dive table.
WARNING
Do not engage in skin diving after scuba diving
since this can have a serious effect on your health.
This watch does not incorporate a function for
distinguishing between scuba diving and skin diving.
CAUTION
Storage of Log Data
Always make sure to keep a separate record of your
important log data.
Various types of data stored by this watch may be lost
in the following cases:
(1) improper use of the watch

WARNING
WARNING
Precautions During Diving
Precautions After Diving
1. Avoid ascending too rapidly.
• A rapid ascent can cause decompression sickness and
other detrimental effects on the body. Maintain a
safe ascent rate.
2. Please note that while in the water, it may be
difficult to hear the depth alarm or other alarm
tones depending on the surrounding conditions and
environment. If this happens, check the LED while
listening for the alarm tone.
3. If the watch should happen to not operate properly
while in the water, begin to ascend immediately.
• Immediately begin to ascend while observing an
ascent rate of no more than 9 m (30 ft)/minute.
4. Dive while allowing a sufficient margin for the nodecompression limit time to ensure safety.
5. In the case you happen to engage in decompression
diving, immediately begin ascending to the surface
while observing an ascent rate of no more than 9 m
(30 ft)/minute.
6. When ascending, always make sure to make
decompression stops according to a dive table to
ensure sofety.
52
1. Avoid flying in an airplane when the surface mode
is operating.
• Make sure to rest sufficiently after diving.
• It is recommended to avoid flying for at least 24
hours following the completion of diving.
2. Carefully rinse off any seawater, mud or sand
adhered to the watch and then wipe off any excess
moisture with a dry cloth.
3. Remove any debris or dirt that has become trapped
in the pressure sensor.
• If debris has become trapped in the pressure sensor,
rinse it out with pure water.
• Do not remove the sensor cover or poke the pressure
sensor with a sharp object. In addition, do not blow

cannot be removed.
4. Always make sure to store (record) important log
data separately.
53
Diving Terms
1. Diving
<No-Decompression Diving and NoDecompression Limit Time (NDL)>
No-decompression diving (no-decompression limit: NDL)
refers to diving during which the diver is able to surface
without stopping for decompression while ascending
following the completion of a dive. The limit time during
which this no-decompression diving is allowed is referred
to as the no-decompression limit time. No-decompression
limit time varies according to the diving depth and diving
time of the previous dives.
<Decompression Diving>
This refers to diving beyond the no-decompression limit
time. Decompression diving is extremely dangerous since
nitrogen accumulates in the body beyond allowed levels.
Do not engage in this type of diving.
<Decompression Stop>
This refers to stopping for the purpose of required
decompression in the event of having engaged in
decompression diving. It is necessary to make
decompression stops at predetermined depths
(decompression stop instructed depth) and at
predetermined times (decompression stop instructed time)
when ascending.
<Safety Stop>
This refers to a temporary pause while ascending in order
to ensure safety and allow nitrogen to be dispelled from
the body even if the no-decompression limit time has not
been exceeded. In the case of diving to a depth of 18 m
(60 ft) or more, always make a safety stop at a depth of 5
m (15 ft) to ensure safety.
<High-Altitude Diving and High-Altitude
Setting>
High-altitude diving refers to diving at a high location 300
m (1,000 ft) above sea level (such as in lakes, ponds or
rivers). When diving in freshwater, water depth is
displayed based on seawater (specific gravity: 1.025).
CAUTION
1. This watch is not equipped with a function that
indicates decompression diving or no-decompression
diving.
2. Make decompression stops and safety stops in
accordance with a dive table.
2. Measurement of Water Depth
Water depth is measured every second, and the current
depth is displayed in 0.1 m (1 ft) increments while diving.
• Measuring range: 1.0 (4 ft) to 100 m (300 ft)
• A depth of 0.0 m (0 ft) is displayed when shallower
than a depth of 1.0 m (4 ft), while "Over M" ("Over
ft") is displayed at a depth of greater than 100 m
(300 ft).
• When there is an error in the measured value for water
depth, the [ ] error mark is displayed instead of the
diver mark.
<Maximum Depth>
This refers to the deepest depth of a single dive.
<Dive Date>
This refers to the date on which a dive was made (year,
month, date).
54
55
3. Measurement of Dive Time
4. Measurement of Water Temperature
The elapsed time of a dive to a depth of greater than 1.0 m
(4 ft) is displayed.
Water temperature can only be measured while in the
water. Measurement of water temperature begins after the
water depth exceeds 1.0 m (4 ft), and the most recent
water temperature is displayed in 1˚C (1˚F) units during
diving.
• Measuring range: -9.9˚C to +40.0˚C (14˚F to 104˚F)
* "--˚C" ("--˚F") is displayed when the measuring range
has been exceeded.
<Dive Time>
This refers to the total amount of time at a depth of greater
than 1.0 m (4 ft) for a single dive.
• Measurement of dive time starts automatically when the
depth first exceeds 1.0 m (4.0 ft), and stops when the
depth again becomes shallower than 1.0 m (4 ft). Dive
time resumes from the time it stopped when water depth
exceeds 1.0 (4 ft) within 10 minutes after measurement
of dive time stopped.
• Dive time is displayed in minutes and seconds up to 99
minutes 59 seconds from the start of measurement and is
displayed in minutes after that time.
• Measuring range: 0 minutes 00 seconds to 999 minutes
59 seconds. When the dive time has exceeded 999
minutes 59 seconds, measurement stops and <--'--"> is
displayed.
<Dive Starting Time>
This refers to the time when the water depth first exceeds
1.0 m (4 ft) after the start of a dive.
<Surface Rest Time>
This refers to the elapsed time from completion of a dive
(surface rest time). This watch measures surface rest time
for up to 24 hours in the surface mode.
56
<Minimum Water Temperature>
This refers to the lowest water temperature during a single
dive.
5. Recording of Log Data
Up to 20 sets of log data can be recorded. When the
number of recorded logs has exceeded 20, the oldest log is
deleted and new data is recorded in its place.
<Single Dive>
A single dive is defined to be from the time a water depth
of 1 m (4 ft) was reached following diving mode ready
status (start of dive) to termination of the diving mode.
6. Termination of the Diving Mode
• The watch returns to the surface mode when button (D)
is pressed for about 2 seconds when 0.0 m (0 ft) is
displayed following completion of diving.
• The watch automatically returns to the surface mode
after about 10 seconds while 0.0 m (0 ft) is displayed
following completion of diving.
57
Dive Alarm Functions
This watch is equipped with various dive alarm functions
to avoid danger and problems as much as possible during
diving.
WARNING
Do not engage in diving that causes a dive alarm
function to activate. The degrees of danger vary
according to experience, physical condition and diving
conditions. Diving cannot be assumed to be safe
simply because a dive alarm is not activated.
CAUTION
In the case a dive alarm has sounded while diving,
first begin to ascend to a shallower depth at an
ascent rate of no more than 9 m (30 ft)/minute to
ensure safety. Since the risk increases the deeper you
dive, multiple dive alarms may be activated and sound
at the same time during diving.

WARNING
• The rubber gaskets and other seals used in this watch
will deteriorate over time and use. If the gaskets and
seals are not checked at regular intervals, their condition
may not be sufficient to guard against the entrance of
moisture. In order to maintain the water resistant quality
of your watch, we recommend you have the gaskets and
seals of your watch inspected by a CITIZEN Authorized
Service Center every two to three years. More frequent
inspections may be necessary if the watch is used in
environments such as chlorinated pools or if the watch is
not rinsed with clear water after use in salt water.
Gaskets and seals used to guard against the entrance of
moisture are considered consumable supplies that are not
covered under the terms of the warranty. Inspections and
any components that need to be replaced in order to
maintain the water resistant quality of the timepiece are
at the expense of the consumer.
• If moisture has entered the watch, or if the inside of the
glass is fogged up and does not become clear for an
extended period of time, do not leave the watch in that
state, but immediately take the watch to a Citizen
Service Center for inspection and repair.
• If sea water enters the watch, place the watch in a box or
plastic bag, and immediately take it in for repair.
Otherwise, pressure inside the watch will increase and
parts (such as the glass and buttons) may come off.
WARNING
Handling of Energy Storage Cell
• Do not attempt to remove the energy storage cell from
the watch. If the energy storage cell must be
unavoidably removed, place it in a location out of the
reach of children to prevent accidental swallowing.
• If the energy storage cell is accidentally swallowed,
contact a physician immediately and seek medical
attention.
94
WARNING
Only Use Specified Energy Storage Cell
• Never attempt to use an energy storage cell other than
the energy storage cell used by this watch. Although the
structure of the watch prevents the watch from operating
if another battery is installed, if a silver battery or other
type of battery is forcibly installed in the watch and the
watch is attempted to be charged with that battery
installed, the battery may rupture resulting in possible
damage to the watch and physical injury. Always make
sure to use the specified energy storage cell when
replacing.
WARNING
Repairs
All parts of this watch, excluding the band, are to be
repaired only at a Citizen Service Center. Please have all
inspections and repairs performed at a Citizen Service
Center.
CAUTION
Keep your watch clean
• The case and band of the watch come in direct contact
with the skin in the same manner as clothing. Metal
corrosion as well as perspiration, dirt, dust and other
unnoticed debris may soil the cuffs and other parts of
your clothing. Try to keep the watch clean at all times.
• Wearing of this watch may cause a rash or itching of the
skin in people with sensitive skin or depending on the
wearer’s physical condition. If you notice that you skin
is affected by the watch, immediately stop wearing it and
consult a physician.
95
<Cleaning the Watch>
• Use a soft cloth to wipe off dirt, perspiration and
moisture from the case and crystal.
• Rinse off dirt from metal bands, plastic bands or rubber
bands with water. Use a soft brush to remove any dirt or
debris stuck between the gaps in metal bands.
• Avoid the use of solvents (such as thinner or benzine) as
they may damage the finish.
<Static Electricity>
Since the IC used in quartz watches is susceptible to static
electricity, the display may become incorrect if the watch
is subjected to intense static electricity like that generated
by a television screen.
<Shocks>
Do not subject the watch to violent shocks such as that
resulting from being dropped on the floor.
CAUTION
Precautions When Wearing the Watch
• Be careful while wearing the watch while holding an
infant or child, by taking the watch off beforehand, to
prevent injury or other accident.
• Be careful when engaged in vigorous exercise or work to
prevent injury and accidents to yourself and others.
• Never wear the watch in a sauna or other locations where
the watch can reach high temperatures since this can
cause burns.
CAUTION
Handling of the Band (Cautions when
Putting on and Taking Off the Watch)
Depending on the structure of the band buckle, be careful
not to injure your fingernails when putting on and taking
off the watch.
<Temperatures>
The watch may not function or stop running if exposed to
temperatures outside the range of 0˚C to 55˚C (32˚F to
131˚F). In addition, although the liquid crystal display
may also become illegible outside this temperature range,
it will return to normal when the watch is returned to
normal temperatures.
96
<Chemical Agents, Gases and Mercury>
Avoid using the watch in environments containing
chemical agents and gases. If solvents such as thinner or
benzine, as well as articles containing such substances
(including gasoline, fingernail polish, cresol, bathroom
cleaners and adhesives) become adhered to the watch,
they can cause discoloration, deterioration and cracking.
Use ample caution when handling chemicals. In addition,
contact with mercury used in thermometers and so forth
can cause the case and band to become discolored.
<Storage>
• When not using the watch for an extended period of
time, carefully wipe off any perspiration, dirt or moisture
from the watch and store in a location preferably free of
high and low temperatures, high humidity.
• When not using your watch for an extended period of
time,it is recommend to store it in a location that is
exposed to light as much as possible.
