Handling Precautions (2)
WARNING
Do not use the watch for scuba diving or saturation diving.
The various tightened inspections under simulated
harsh environment, which are usually required for
watches designed for scuba diving or saturation
diving, have not been conducted on this watch. For
diving, use special watches for diving.
The radio waves emitted from this product may have
a negative impact and cause an accident due to a
malfunction.
Do not use this product near medical equipment.
・
The radio waves may affect pacemakers and
electric medical equipment . Do not use it in
crowded places such as packed trains, and inside
of medical institutions.
Do not use this product near automatic control devices
・
such as automatic doors and fire alarm systems.
In the places where transmission of radio waves
is prohibited, such as in airplanes, turn off the
automatic reception function of the watch, and do
not perform manual reception.
The radio waves emitted from this product may
adversely affect other devices.
CAUTION
Do not pour running water directly from faucet onto
the watch.
The water pressure of tap water from a faucet is high
enough to degrade the water resistant per formance of
a water resistant watch for everyday life.
Do not push the buttons when the watch is wet.
Water may get inside of the watch.
If the inner surface of the glass is clouded with
※
condensation or water droplets appear inside of the

of the watch is deteriorated. Immediately consult the
retailer from whom the watch was purchased or SEIKO
CUSTOMER SERVICE CENTER .
Do not leave moisture, sweat and dirt on the watch
for a long time.
Be aware of a risk that a water resistant watch may
lessen its water resistant performance because of
deterioration of the adhesive on the glass or gasket, or
the development of rust on stainless steel.
Do not wear the watch while taking a bath or a
sauna.
Steam, soap or some components of a hot spring
may accelerate the deterioration of water resistant
performance of the watch.

In addition to the time display function, the watch is equipped with
perpetual calendar and Simplified World Time Function.
Time Synchronization via Bluetooth Communication
■
Time data is transmitted between the watch and the dedicated
application via Bluetooth communication to correct the time/calendar
of the watch. The data can be received either automatically or
manually as required by operating the button. The watch indicates
whether the reception has succeeded or failed.

By setting the city hand to a desired city initial on the dial, the time
of five cities in the world can be indicated by the hands. When the
time is synchronized either automatically or manually via Bluetooth
communication, the city hand moves to the initial of the current location.
Battery Life Indicator
■
When the battery nears its end, the city hand locks in the 9 o'clock
direction to warn that it needs to be replaced with a new one
immediately. (Once in this state, the operations of all of the buttons
become disabled (the buttons do not function).)

Band
The band touches the skin directly and becomes dirty with sweat
or dust. Therefore, lack of care may accelerate deterioration of
the band or cause skin irritation or stain on the sleeve edge. The
watch requires a lot of attention for longer use.
Metallic band
●
・ Moisture, sweat or soil will cause rust even on a stainless steel band
if they are left for a long time.
・ Lack of care may cause a yellowish or gold stain on the lower sleeve
edge of shirts.
・
Wipe off moisture, sweat or soil with a soft cloth as soon as possible.
・ To clean the soil around the joint gaps of the band, wipe it out in
water and then brush it off with a soft toothbrush.
（Protect the watch body from water splashes by wrapping it up in
plastic wrap etc.
・
Because some titan bracelets use pins made of stainless steel, which
has outstanding strength, rust may form in the stainless steel parts.
・ If rust advances, pins may poke out or drop out, and the watch case
may fall off the bracelet, or the clasp may not open.
・ If a pin is poking out, personal injury may result. In such a case,
refrain from using the watch and request repair.
Leather band
●
・ A leather band is susceptible to discoloration and deterioration from
moisture, sweat and direct sunlight.
・ Wipe off moisture and sweat as soon as possible by gently blotting
them up with a dry cloth.
・ Do not expose the watch to direct sunlight for a long time.
・ Please take care when wearing a watch with light-colored band, as
dirt is likely to show up.
・ Refrain from wearing a leather band watch other than Aqua Free
bands while bathing, swimming, and when working with water even
if the watch itself is water-resistant enforced for daily use （10- or 20-
BAR water resistant）.
）
Silicone band
●
・ As for material characteristics, the band is easily dirtied, and may
be stained and discolored. Wipe off dirt with a wet cloth or cleaning
tissue.
・ Unlike bands of other materials, cracks may result in the band being
cut. Take care not to damage the band with an edged tool.
Polyurethane band
●
・ A polyurethane band is susceptible to discoloration from light, and
may be deteriorated by solvent or atmospheric humidity.
・ Especially a translucent, white, or pale colored band easily adsorbs
other colors, resulting in color smears or discoloration.
・ Wash out dirt in water and clean it off with a dry cloth.
（Protect the watch body from water splashes by wrapping it up in
plastic wrap etc.
・ When the band becomes less flexible, have the band replaced with
a new one. If you continue to use the band as it is, the band may
develop cracks or become brittle over time.
Notes on skin
irritation and
allergy
Notes on the
length of the
band
）
Skin irritation caused by a band has various
reasons such as allergy to metals or leathers, or
skin reactions against friction on dust or the band
itself.
Adjust the band to allow a little
clearance with your wrist to ensure
proper airflow. When wearing the
watch, leave enough room to insert
a finger between the band and your
wrist.

Remarks on Battery
1. Notes on the battery
(1) Battery life
This watch keeps operating for approximately 4 years if a new normal
battery is inserted in it.
※ If the time synchronization via the Bluetooth communication is used
more than once a day, however, the watch may run down in less
than 4 years.
(2) Monitor battery
The battery in your watch is a monitor battery which is inserted at the
factory to check the function and performance of the watch. Its actual
life once in your possession may be less than the specified period.
(3) Battery replacement
・For battery replacement, be sure to have the battery replaced with
a new one at the retailer from whom the watch was purchased,
specifying a genuine SEIKO battery.
・If the old battery is left in the watch for a long time, a malfunction
may be caused due to battery leakage, etc. Have it replaced with a
new one as soon as possible.
・Battery replacement is made at cost even if it runs down within the
guarantee period.
・Once the case back is opened for battery replacement or other
purposes, the original water resistant quality designed for the
watch may deteriorate when it is closed. When you have the battery
replaced with a new one, also request the water resistance test
suitable for the water resistant quality of your watch. If your watch
has 10-bar or higher water resistant quality, be sure to have such
test performed on the watch every time the battery is replaced.
Please note that it takes several days to check the water resistant
quality of your watch. When requesting the checking, therefore,
please confirm the period required for it.
・If the watch stops operating soon after the battery is replaced with
a new one, it needs to be overhauled. (Refer to P. 25.)
2. Battery life indicator
The watch is equipped with a battery life indicator that enables you to
know when the battery needs to be replaced.
When the city hand is locked at the 9 o'clock position, the watch may
※
run down in a week or so.
3. Initial setup after replacing battery
After replacing the battery, be sure to perform a system reset operation
