WARNING

About This Product

※

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).

CAUTION

Do not wear the watch while taking a bath or a

sauna.

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 pour running water directly from faucet.

Do not leave moisture, sweat and dirt on the

watch for a long time.

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.

Steam, soap or some components of a hot spring may accelerate the

deterioration of water resistant performance of the watch.

WARNING

CAUTION

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.

Do not turn or pull out the crown when the

watch is wet.

Water may get inside of the watch.
