There are time differences around the world based on Coordinated Universal Time
(UTC). There are 24 regions (Time Zones) around the world with a time difference
of one hour. This system has been adopted internationally by setting the total time
difference around the world as 24 hours.
In addition, Daylight Saving Time (Summer Time) is individually adopted in some regions.
Coordinated Universal Time (UTC)
UTC is the universal standard time coordinated through an international agreement.
This is used as the official time for recording time around the world. The time
obtained by adding a leap second to the International Atomic Time (TAI) determined
based on the atomic clock around the world and coordinated in order to compensate
for deviations from universal time (UT) which is astronomically determined is the UTC. 5
Daylight Saving Time (Summer Time) is in effect in
time zones indicated with a ★ mark.
(As of January 2014)
Summer time (DST) : Daylight Saving Time
Summer time is daylight saving time. Advancing the watch one hour to prolong
daytime during longer daylight hours in summer. Daylight saving time has
been adopted in about 80 countries, mainly in Europe and North America. The
adoption and duration of daylight saving time vary depending on the country.
If a receivable official standard frequency is indicated with a △ mark, summer time in the time zone
can be set by receiving the frequency if the time zone is within the radio signal reception range.
※ Time differences between regions and daylight saving time may change due to circumstances of a country or region.
※ A time difference established in 15 minute or 30 minute units is adopted in very limited regions (ex. India).

Keep the watch more than 1 cm away from
magnetic products. (JIS level-2 standard)
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under
normal use, the watch needs to be demagnetized. In this case, you will be charged for demagnetization and
accuracy readjustment even if it happens within the guarantee period.
The reason why watch is affected by magnetism
The built-in motor is provided with a magnet, which may be influenced by a strong external magnetic field.
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 long usage.
● 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).
● 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
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.
Notes on the
length of the band
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.

Power source
The battery used in this watch is a special secondary battery, which is totally different from ordinary silver oxide batteries.
Unlike other disposable batteries such as dry-cell batteries or button cells, this secondary battery can be used over and
over again by repeating the cycles of discharging and recharging.
However, for various reasons such as long-term use or usage conditions, the capacity or recharging efficiency of the
secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the efficiency of the secondary battery decreases, have the watch repaired.
NOTICE
■ Remarks on replacing the secondary battery
・Do not remove the secondary battery yourself.
・Replacement of the secondary battery requires professional
knowledge and skill. Please ask the retailer from whom the watch
was purchased for repair.
・Installation of an ordinary silver oxide battery can generate heat that can
cause bursting or ignition.
※ Overcharge prevention function
When the secondary battery is fully charged, the overcharge prevention function
is automatically activated to avoid further charging. There is no need to worry
about damage caused by overcharging no matter how much the secondary
battery is charged in excess of the "time required for fully charging the watch".
※ Refer to "Standard charging time" on page 111 to check the time required for fully charging the watch.
NOTICE
■ Notes on charging the watch
・When charging the watch, do not place the watch in close proximity
to an intense light source such as lighting equipment for photography,
spotlights or incandescent lights, as the watch may be excessively heated
resulting in damage to its internal parts.
・When charging the watch by exposure to direct sunlight, avoid places that
easily reach high temperatures, such as a car dashboard.
・Always keep the watch temperature under 60℃ .

Lumibrite is a luminous paint that absorbs the light energy of the sunlight and lighting apparatus in a short time and stores it
to emit light in the dark.
For example, if exposed to a light of more than 500 lux for approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours.
Please note, however, that, as Lumibrite emits the light it stores, the luminance level of the light decreases gradually over time.
The duration of the emitted light may also differ slightly depending on such factors as the brightness of the place where the
watch is exposed to light and the distance from the light source to the watch.

Preliminary position
When the time are not correct even if the radio signal reception is
successful, the preliminary position of the date may be misaligned.
Troubleshooting
Troubleshooting
The possible causes of misalignment of preliminary position are as follows:
・In the case of having a strong impact: the misalignment may occur
when dropping or hitting the watch.
・In the case of a magnetic influence: the misalignment may occur when
bringing the watch close to an object which generates magnetism.
→ Examples of magnetic products that may affect watches P.125
The condition the preliminary position of hand is misaligned means that compared to a health meter,
the zero position of a meter is misaligned, causing a correct weight not to be displayed.
■ Automatic hand position adjustment function (function to automatically
adjust the preliminary position of the hour, minute, and second hands)
The hour, minute, and second hands have an Automatic Hand Position Adjustment
Function, which automatically corrects an incorrect preliminary position.
Automatic Hand Position Adjustment Function activates once an hour for the
minute and second hands and at 12:00 both for AM and PM for the hour hand.
