• Water-resistance for daily use (to 3 atmospheres): This type of watch is water-
resistant to minor exposure to water. For example, you may wear the watch
while washing your face; however, it is not designed for use underwater.
• Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch
is water-resistant to moderate exposure to water. You may wear the watch
while swimming; however, it is not designed for use while skin diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of
watch may be used for skin diving; however, it is not designed for scuba or
saturated diving using helium gas.
CAUTION
• Be sure to use the watch with the crown pressed in (normal position). If your
watch has a screw-type crown, be sure to tighten the crown completely.
• Do NOT operate the crown or button with wet fingers or when the watch is wet.
Water may enter the watch and compromise water-resistance.
• If the watch is used in seawater, rinse with fresh water afterward and wipe with
a dry cloth.
• If moisture has entered the watch, or if the inside of the crystal is fogged up
and does not become clear within a day, immediately take the watch to your
dealer or Citizen Service Center for repair. Leaving the watch in such a state
will allow corrosion to form inside.
