•
The SEIKO Diver's
Watch is specially
designed for scuba
diving, featuring an
excellent water
resistant quality.
•
As a diver's watch is so
designed and
fabricated as to fully
perform its functions.
You can be confident
in your watch.
•
To enjoy long service
life, you are requested
to carefully read this
instruction booklet and
use your watch
This section explains the
precautions to be
observed before, while
and after diving. Be sure
to observe each of them
to enjoy safe diving.
• The watch is designed for in use scuba diving using
heavy breathing apparatus. It can withstand water
pressure up to a depth of 200 m. Never use the
watch, however, in saturation diving using helium gas.
• While diving, never operate the watch in any other
manner than set forth in the instruction manual.
CARE OF YOUR WATCH
• After using the watch in seawater, for example in diving, rinse it in fresh
water and wipe it thoroughly dry. Do not use chemicals to wash the watch.
• The case and bracelet touch the skin directly just as underwear. If they
are left dirty, the edge of a sleeve may be stained with rust of those who
have a delicate skin may have a rash.
• After removing the watch from your wrist, wipe perspiration or moisture
with a soft cloth. This will prevent the watch from being soiled, adding to
the life of the gasket.
• Please clean the rotating bezel regularly. Otherwise, dust will gather
under it, making the rotation harder.
(
SOFT PLASTIC BRACELET
)
• The bracelet made of soft plastics does not require special care. If it
gets dirty, however, it may cause trouble to the skin. Rinse it with soapy
water from time to time. Since it is a chemical product, it may
deteriorate by the use of solvents. The band will become hardened or
discolored after several years of use. In that case, replace it with a new one.
RASH AND ALLERGY
• Adjust the bracelet or band so that there will be a little clearance
between the bracelet or band and your wrist to avoid accumulation of
perspiration.
• If you are constitutionally predisposed to rash, the band may cause you
to develop a rash or an itch depending on your physical condition.
• The possible causes of the rash are as follows:
1. Allergy to metals or leathers
2. Rust, dust or perspiration on the watch or band
• If you develop any skin reactions, take off the watch and consult a
doctor immediately.
• Before using the diver's watch, you have to be
properly trained in various types of diving and possess
the requisite experience and skill to dive safely. When
diving, strictly abide by the rules of diving.
• Do not attempt to dive using the watch unless you
have thoroughly familiarized yourself with the
operation and maintenance of the watch, and have
tested all watch functions prior to each dive. It is
absolutely essential that you observe strictly all
instructions for the use and maintenance of the watch
set forth in this manual.

• SEIKO makes it policy to usually keep a stock of spare parts for its
watches for 7 years. In principle, your watch can be reconditioned
within this period if used normally. (Replacement parts are those
which are essential to maintaining the functional integrity of the watch.)
• The number of years that a watch is considered repairable may vary
greatly depending on the conditions under which it was used, and
normal accuracy may not be achieved in some cases. We
recommend, therefore, that you consult the retailer from whom the
watch was purchased when having them repair your watch.
• The case, dial, hands, glass and bracelet, or parts there of may be
replaced with substitutes if the originals are not available.
PLACES TO KEEP YOUR WATCH
• If the watch is left in a temperature below 10 or above
+60 for a long time, it may function improperly or stop
operating.
• Do not leave the watch in a place where it is subjected to
strong magnetism or static electricity.
• Do not leave the watch where there is strong vibration.
• Do not leave the watch in a dusty place.
• Do not expose the watch to gases or chemicals.
(Ex.: Organic solvents such as benzine and thinner,
gasoline, nail polish, cosmetic spray, detergent, adhesives,
mercury, and iodine antiseptic solution.)
• Do not leave the watch in a hot spring, or do not keep it in a
drawer having insecticides inside.
PRECAUTIONS ON WEARING YOUR WATCH
Take utmost care in the following cases:
• When clasping and unclasping the band, you may damage
your nail, depending on the type of clasp used with the
band.
• In case you tumble and fall or bump into others with the
watch worn on your wrist, you may be injured by the reason
of the fact that you wear the watch.
• When you make contact with children,
especially with infants, they may get injured or
develop a rash caused by allergy.
PERIODIC CHECK
• It is recommended that the watch be checked
once every 2 or 3 years. A periodic check will
prevent any damage from insufficient
lubrication, entrance of moisture or perspiration,
etc. and ensure longer use. To have it checked,
take your watch to the retailer from whom the
watch was purchased. Your watch will be sent
to the SEIKO SERVICE CENTER to undergo a
thorough checking work is done. Depending on
the result of checking, adjustment or repair may
be required.
• When replacing parts, please specify that only
genuine SEIKO parts be used. If the watch has
a urethane band, it will lose its elasticity and
become hardened gradually over time. In that
case, have it replaced with a new one by the
retailer from whom the watch was purchased.
2 There are no scratches or cracks
on the band and crystal glass.
3 The band is firmly secured to the case.
Unlike the conventional quartz watch powered by the button-type
battery, the SEIKO DIVER SCUBA 5M43 is the diver watch that is
equipped with an automatic power generating system developed by
SEIKO. It generates the electrical energy to power the watch, utilizing
the movement of the arm or wrist, and stores it in KINETIC E.S.U. So,
the watch does not use a battery, and the battery replacement
procedures are completely eliminated. The watch features a power
reserve indicator function that shows with the movement of the second
hand how many days of power reserve is stored in KINETIC E.S.U. If
fully charged, the watch will keep operating for more than 7 days.
CAUTION
• The movement of the arm while the watch is worn causes the
automatic power generating system to work, and the watch is
powered by the electrical energy thus generated. Therefore, the
watch will not be charged while left unused.
• As a guideline of charging, it is recommended that the watch be
worn on your wrist daily for more than 10 hours.
• When the energy stored in KINETIC E.S.U. is reduced to an
extremely low level, the second hand starts moving at two-
second interval instead of the normal one-second interval,
indicating that the watch needs recharging. Please see "4-1
How to charge the watch".

hand
hand
1 Swing the watch from side to side rhythmically at a rate of
twice a second as shown in the illustration. Approximately
100 swings will reserve up to 6 hours of power. The
second hand starts moving at the normal one-second
interval instead of two-second interval.
2 Swing the watch further until the second hand starts
moving at one-second interval. At that stage, there will be
about 3 hours of power reserve available. It is
recommended that the watch be swung further until
approximately 1 day of power reserve is stored in
KINETIC E.S.U. If fully charged, the watch will keep
operating for more than 7 days. It is not necessary,
however, to fully charge KINETIC E.S.U. at this step.
200 to 250 swings are required at to reserve one day of powe r
.
The current power reserve of KINETIC E.S.U. can be
checked by using the power reserve indicator function.
(Refer to "4-2 How to use the power reserve indicator" at
right.)
KINETIC
E.S.U.
KINETIC E.S.U
The watch is equipped with a system to prevent
overcharge. Even
if it is further swung after being fully
charged, no malfunction will result
.
To charge KINETIC E.S.U. efficiently,
swing the watch from side to side,
drawing an arc of about 20 cm.
Even if the watch is swung extremely
quickly with vigor, it will not be
charged efficiently.
When the watch is swung, the
oscillating weight in the generating
system rotates to drive the
mechanism. As it rotates, it gives out
sound, which is not a malfunction.
• The power reserve stored in
KINETIC E.S.U. can be
checked by using the power
reserve indicator function.
• The power reserve indicator
shows how many days the
power reserve in KINETIC
E.S.U. can keep the watch
operating.
• By pressing the button, the
second hand advances quickly
by a certain amount of seconds
depending on the power reserve
in KINETIC E.S.U.
• Besides using while the watch is
in use, the power reserve
indicator is particularly useful for
checking the power reserve
before you leave the watch
unused for a long time.
<How to read the power reserve
indicator>
The power reserve stored in
KINETIC E.S.U. is classified into
four levels and represented by
the number of seconds that the
second hand advances. The
power reserve indicator gives a
rough indication of the power
reserve and, therefore, does not
indicate the exact period of time
during which the watch keeps
operating without being charged.
5second
6 hours ~ 2 day 2 ~ 4 day 4 ~ 7 day More than 7 days
10second 20second 30second
<Example>
If the second hand advances "20 seconds" by pressing the button, 4 to 7 days of power reserve is available.
The watch will keep operating for at least 4 days without being charged, but the exact duration (4 days or 7
days) cannot be known.
The power reserve indicator provides a general guideline of the duration within which the watch keeps
operating without being charged. Actual power reserve may differ slightly from the amounts in the table.
After the second hand moves quickly by a certain amount of seconds, it stops on the spot until the current
time catches up with the time the second hand indicates.
You can immediately press the button again to recheck the power reserve one more time. To do so a third
time, however, wait until the second hand resumes normal movement before pressing the button again.
Please note that the power reserve indicator cannot be used while the second hand is moving at two-
second interval.

Phenomenon Possible cause Remedies
The rotating bezel is not turning
smoothly.
Dust or soil or sand or the like may stick
between the case and the rotating bezel.
Please rinse the watch in fresh water. If it cannot be washed out,
take your watch to the watch retailer from whom it was purchased.
When the power reserve is checked
by pressing the button, the second
hand will not move more than 10
seconds even if you wear the watch
daily on your wrist.
You wear the watch daily but only for a short
time, or you lead a relatively sedentary life,
which does not involve much arm movement.
Wear the watch on your wrist as long as possible. It is recommended
that the watch be worn for more than 10 hours a day at least for 3
consective days. The second hand will advance 20 or 30 seconds by
pressing the power reserve indicator button, indicating the power
reserve in KINETIC E.S.U. has been increased.
Blur in the display persists. Small amount of water has got inside the watch
due to deterioration of the gasket,etc.
Consult the retailer from whom the watch was purchased.
The date (day) changes at 12 o'clock noon.
AM/PM is not properly set. Advance the hands by 12 hours.
The second hand moves at two-
second interval.
The electrical energy stored in KINETIC E.S.U.
has been reduced to an extremely low level.
The watch may stop operating in 6 hours. Charge the watch
referring to "4-1 HOW TO CHARGE THE WATCH."
The watch gains/loses time.
• The watch has been left in extremely high or
low temperature for a long time.
• This condition will be corrected when the watch temperature
returns to normal.
• The watch was brought into close contact with
a magnetic object.
• This condition will be corrected when the watch is kept away from
close contact with the magnetic source.
• You dropped the watch, hit it against a hard
surface or wore it while playing active sports.
• The watch was exposed to strong vibrations.
• This condition will not be corrected. Have the watch checked by
the retailer from whom the watch was purchased.
The watch has stopped operating. All the electrical energy stored in KINETIC
E.S.U. has been used up.

WATCH.
<Quick movement of the second hand by 30
seconds>
• If KINETIC E.S.U. has been fully charged, the
second hand advances 30 seconds by pressing
the button, meaning the watch keeps operating
for at least 7 days without being charged.
• The watch will keep operating for 7 to 14 days,
but the exact duration of charge cannot be
known.
• If KINETIC E.S.U. is fully charged, the watch will
keep operating for approximately 14 days
(2week).
(When the second hand moves at two-second
interval )
• If you find the second hand moving at two-second
interval while the watch is in use or while it is left
unused, the watch may run down in six hours.
Therefore, be sure to swing the watch and
recharge the watch. (See "4-1 How to charge the
watch.")

PRECAUTIONS ON KINETIC E.S.U
WARNING
Never insert a miniature silver oxide battery
instead of KINETIC E.S.U.
• Instead of a silver oxide miniature battery, KINETIC
E.S.U. is used to power the watch. Therefore, unlike
an ordinary miniature battery, battery replacement is
not necessary.
• Even while the second hand is stopped by pulling the
crown, the current is consumed to control the built-in
IC. Please note, therefore, that, while the watch is not
in use, pulling the crown will not save the energy
stored in KINETIC E.S.U.
