safety regulations are not strictly observed.
Immediately stop wearing the watch in following cases:
○ If the watch body or band becomes edged by corrosion etc.
○ If the pins protrude from the band.
* Immediately consult the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE
CENTER.
Keep the watch and accessories out of the reach of babies and children.
Care should be taken to prevent a baby or a child accidentally swallowing the accessories.
If a baby or child swallows the battery or accessories, immediately consult a doctor, as it will be
harmful to the health of the baby or child.
Do not remove the secondary battery from the watch.
* About the secondary battery → Power Source → P.44
Replacement of the secondary battery requires professional knowledge and skill. Please ask the retailer
from whom the watch was purchased for replacement of the secondary battery.
Installation of an ordinary silver oxide battery can generate heat that can cause bursting and ignition.
b WARNING
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 watches specifically designed for diving.
b CAUTION
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.
