although your watch has been through vigorous
static pressure testing, it is worth remembering
that there are many variables that can affect
the water resistance of your watch.
for instance, arm movements during swimming
and the sudden impact of diving and water
sports will drastically increase the pressure the
watch is under. Wearing your watch in the bath,
shower, or sauna can also have an effect as a
rapid increase in temperature can cause seals
to expand and in extreme cases, malfunction or
create condensation.
for these reasons, the water resistance rating
of your watch (as shown)
should only ever
be considered a guideline and we strongly
recommend they are always adhered to.
1 ATM (10 mETREs)
safe to wear your watch while
washing your hands with tap water.
3 ATM (30 mETREs)
Washing your car and/or general
hose pipe usage.
5 ATM (50 mETREs)
Water resistant to most household
shower units.
10 ATM (100 mETREs)
safe to use while snorkelling in
open water.
30 ATM (300 mETREs)
Ideal for experienced divers and
those practising scuba-diving.
50 ATM (500 mETREs)
professional divers, experiencing
prolonged exposure underwater.
100 ATM (1000 mETREs)
professional deep sea diving.
