To Preserve The Quality Of Your Watch; Performance And Caliber Of Your Watch; Water Resistance; Magnetic Resistance （Affect Of Magnetic Field - Seiko Spring Drive 9R65 Instructions Manual

■ TO PRESERVE THE QUALITY OF YOUR WATCH

The watch needs frequent attention.
・ Wipe away moisture, sweat or dirt frequently with a soft dry cloth.
To clean the clearances （around the metallic band, crown, case back or rotating
bezel） , a soft toothbrush is convenient.
・ After soaking the watch in seawater, be sure to wash the watch in clean pure water
and wipe it dry carefully.
62
Turn the crown from time to time
・ In order to prevent corrosion of the crown, turn the crown from time to time.
・ The same practice should be applied to a screw lock type crown.
⇒ ● "Screw lock type crown" page 50

Refer the table below for the description of each degree of
water resistant performance of your watch before using.

Do not use the watch in 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 the water-resistant watch with the BAR (barometric
pressure) display. For diving, use special watches for diving.
66
Do not turn or pull out the crown 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 watch for a long time, the water resistant performance of the
watch is deteriorated. Immediately consult the retailer from whom the watch was
purchased or SEIKO CUSTMER SERVICE CENTER (listed on the end of a book).
● Magnetic resistance （affect of magnetic field）
・ Grand Seiko Spring Drive conform to the Magnetic Resistance Standard of JIS Class 1.
The watch has magnetic resistance to maintain performance in most cases even where it
is brought close to （at least 5cm spaced from） equipment generating a magnetic field in
normal life. However, the movement parts are magnetized when they encounter a strong
magnetic field, thereby accuracy may go out of order. Pay attention so as not to bring the
watch close to equipments generating a strong magnetic field within 5cm.

Class 1 4800A/m
・ If the accuracy exceeds the accuracy target range （ ± 15 seconds/month） during
normal usage due to magnetization, removal of magnetism and accuracy readjustment
works are charged regardless of the guarantee period.
Keep the watch more than 5 cm away from magnetized products.

（on the case back）
The watch has magnetic resistance to maintain performance in
most cases where it is brought close to （at least 5cm spaced
from） equipment generating a magnetic field in normal life.

※ The above figures are examples. Both of them may be different from the figure on the case back of your watch.
Condition of use
Avoid drops of water or sweat
The watch withstands accidental contact
with water in everyday life.
The watch is suitable for sports such as swimming.
The watch is suitable for diving not using an air cylinder.
CAUTION
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.
Do not pour running water directly from faucet.
The water pressure of tap water from a faucet is high enough to degrade
the water resistant performance of a water resistant watch for everyday
life.
● Magnetized items that may affect watches

・ Magnetic clips ・ Magnetic accessories
・ Magnetic health equipments （such as magnetic ・ Magnetic door seal of
plasters, magnetic pillows, magnetic back belts etc.） refrigerator or furniture
