Affected by nearby magnetism,
a watch may temporarily gain or lose time or stop operating.
※ When the hand positions deviate to display incorrect time as a result of influence of magnetism. this
watch automatically corrects the hand alignment itself. (Refer to p.134)
Indication on the case back Condition of use
No indication
Keep the watch more than 10 cm away from
magnetic products.
Keep the watch more than 5 cm away from
magnetic products. (JIS level-1 standard)
Keep the watch more than 1 cm away from
magnetic products. (JIS level-2 standard)
Magnetic resistance
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the spec-
ified 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.

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-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 the
length of the band
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.
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.
