WARNING: Confirm water resistance performance of your watch

Refer to the watch dial and/or 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 “1 BAR” is roughly equal to 1 atmosphere.
“BAR” may also be represented as “bar”.

!

“W.R.” may also be represented as “WATER RESIST” or “WATER RESISTANT”.
All the descriptions mean that watches with them have a certain water resistance.

No indication Non water-resistant
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 RESIST Water-resistant to 3 atmospheres (Everyday use water-resistant watch)
Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for occasional accidental splashing.
W. R. 5 bar Water-resistant to 5 atmospheres (Upgraded everyday use waterresistant watch)
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.
W. R. 10 bar
W. R. 20 bar
Water-resistant to 10 or 20 atmospheres (Upgraded everyday use waterresistant watch)
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.
DIVER'S 200m
