CAUTION
Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch.
※ Should blur or moisture occur inside the dial glass and persist for a long time, this
indicates poor waterproof capability. Consult the retailer from whom the watch
was purchased or SEIKO CUSTOMER SERVICE CENTER as soon as possible.
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.
