Precautionary Items and Usage Limitation
WARNING Water Resistance
• Water-resistance for daily use (to 3 atmospheres) means that the
watch may be worn while washing your face or in the rain, but is not
to be immersed in water.
• Upgraded water resistance for daily use (up to 5 atmospheres) means
that the watch may be worn while swimming, but is not to be worn
while skin diving or scuba diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres)
means that the watch may be worn while skin diving, but not while
scuba or saturated diving using helium gas.
• Refer to the watch dial and the case back for the indication of the water resistance of your watch. The
following chart provides examples of use for reference to ensure that your watch is used properly.
• WATER RESIST (ANT) xx bar may also be indicated as W.R. xx bar.
(The unit “bar” is roughly equal to 1 atmosphere.)
