Water Resistance
Water resistance testing of watches is rated in a laboratory by
pressure tests done on a watch in a static position. However,
many water based activities involve a lot of movement and
involve other environmental changes. These exceptions to
how the watch is rated may challenge or eliminate the water
protection features of a water resistant watch. In particular,
the water resistance rating of a watch does not take into
account sudden, rapid and repeated water pressure changes,
high water temperatures and sudden changes of tempera-
ture.
Do not wear your watch in the shower or bath as this can affect
its water resistance. Steam can penetrate rubber gaskets,
cause condensation on the crystal and rust the movement. In
addition, sudden temperature changes can adversely affect
the watch. If your watch is equipped with a screw down crown,
make sure it is in the locked position to ensure its water
resistance.
