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.
