such as accidental contact with splashes of water or rain, but it
is not designed for wearing while swimming or diving.

● Water resistance (10 bar/15 bar/20 bar)*
If "WATER RESISTANT 10 BAR", "WATER RESISTANT 1 BAR"

10 bar/1 bar/0 bar, respectively, and is suitable for wearing

* Before using a water resistant 5, 10, 15 or 20 bar watch in water, make
sure the crown is pushed in completely.
Do not operate the crown when the watch is wet or in water. If used in
sea water, rinse the watch in fresh water and dry it completely.

* When taking a shower while wearing a water resistant 5 bar watch, or tak-
ing a bath while wearing a water resistant 10, 15 or 20 bar watch, make
sure to observe the following:
• Do not operate the crown when the watch is wet with soapy water or
shampoo.
• If the watch is left in warm water, a slight time loss or gain may be
caused. This condition, however, will be corrected when the watch re-
turns to normal temperature.
NOTE:
Pressure in bar is a test pressure and should not be considered as corre-
sponding to an actual diving depth since swimming movements tend to in-
crease the pressure at a given depth. Care should also be taken when diving
with the watch into water.
PRECAUTIONS ON WEARING YOUR WATCH
• Exercise care when you hold an infant or small child while wearing the
watch on your wrist, as the infant or child may be injured or develop an
allergic reaction caused by direct contact with the watch.
• Avoid undue shocks such as dropping or scratching against hard surfaces
or playing active sports, which may cause temporary malfunctions.
• There is a possibility of injury caused by wearing the watch on your wrist
especially if you fall down or bump into other people or objects.
