Band

The band touches the skin directly and becomes dirty from 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.

Wipe off the remaining moisture with a soft cloth.

○ Because some titanium 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

○ 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 swimming,

and when working with water even if the watch itself is water-resistant enforced for daily

use (10-BAR/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 wet 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.

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.

Magnetic resistance (Magnetic influence)

Affected by nearby magnetism, a watch may temporarily gain or lose time or stop operating.

Indication on the case

back

Conditions of use

Certified level

No indication

 * For diver’s model

Keep the watch more than 5 cm away

from magnetic products.

4,800 A/m

Keep the watch more than 1 cm away

from magnetic products.

16,000 A/m

MAGNETIC RESISTANT

40000A/m

The watch can maintain its

performance in most cases where it is

brought close to (at least 1 cm spaced

from) magnetic products not only in

normal daily life circumstances but

also in a special work environment.

40,000 A/m

 * A/m (ampere meter) is the international unit (SI unit) for indicating the magnetic field.
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified

rate under normal use, the watch may need to be demagnetized. In this case, you will be charged

for demagnetization and accuracy readjustment even if it happens within the guarantee period.

Examples of common magnetic products that may affect watches

The reason why this watch is affected by magnetism

The built-in speed-regulating mechanism is provided with a magnet, which may be influenced by

a strong external magnetic field.
