Water resistance
• 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. (The unit “1bar” is roughly equal to 1 atmosphere.)
• WATER RESIST(ANT) ××bar may also be indicated as W.R.××bar.
• Non-water resistant models are not designed to come into contact with any moisture. Take care
not to expose a watch with this rating to any type of moisture.
• Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for
occasional accidental splashing.
• Upgraded water-resistance for daily use (to 5 atmospheres) means that the watch may be worn
while swimming, but is not to worn while skin 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.
