b WARNING
1
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.
