• Refer to the watch dial and the case back for the indication of the water resistance of your
watch. e following chart provides examples of use for reference to ensure that your watch
is used properly. (e unit “1 bar” is roughly equal to 1 atmosphere.)
• WATER RESIST (ANT) ××bar may also be indicated as W.R.××bar.

water.
• 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 (to 5 atmospheres) means that the watch may be
worn while swimming, but is not to worn while skin diving.

be worn while skin diving, but not while scuba or saturated diving using helium gas.
