WATER RESISTANT WATCHES


FR?D?RIQUE
CONSTANT EXPLAINS “WATER RESISTANCE”

 


ISO
2281 Water resistant testing


 “
A watch
is not water resistant unless stated on the dial or case back.


Watches,
which are not noted as water resistant, should not be worn whilst washing
hands, dishes or showering etc.


The
notation of water resistance to a given depth (e.g. 30m, 50m) is based on
the fact that the case has been designed to withstand a static laboratory
test to the stated depth for short periods only. Most water resistant
watches are not designed for prolonged and active use in water.


The
only watches designed to withstand these types of conditions are
professional divers watches.”

 


GENERAL
POINTS

The
figures quoted refer to static pressure. The actual water pressure on the
watch during use will be greater than the static pressure. For instance,
diving pressure on the watch is clearly greater at the impact point with
the water during poolside diving.


Condensation
can also be a problem. A sealed watch will pick up body warmth in water
and this remains in the case. If the watch is then suddenly plunged into
water that is some degrees colder, moisture can then be created within the
watch and become visible as small droplets under the glass.

This normally dissipates of its
own accord once the watch is removed from the water, but this not always
the case. The watch may then need to be returned to the watchmaker for
inspection.
