WARNING
Not suitable for swimming
The watch withstands accidental
contact with water in everyday life.

CAUTION
Do not use the watch in scuba diving or
saturation diving.
Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch.
The various tightened inspections under simulated harsh environment, which
are usually required for watches designed for scuba diving or saturation diving,
has not been conducted on the water-resistant watch with the BAR （barometric
pressure） display. For diving, use special watches for diving.

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.
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 the deterioration of the adhesive on the glass or
gasket, or the rust of stainless steel.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of hot spring may accelerate the
deterioration of water resistant performance of the watch.
