Waterproof properties
The water resistance of your DETOMASO watch has been tested to be 5
ATM.
This means that it is splashproof and that you may wash your hands or
take a bath with it. However, the watch is not to be worn in the shower or
when swimming or diving. Waterproofness is not a permanent characte-
ristic; it should be tested annually and in particular before the watch is put
under exceptional strain, as the seals deteriorate gradually in daily use.
The seals are the important factor in guaranteeing the waterproofness
of a watch. These age naturally and are also affected by perspiration and
acids.
ISO 2281 stipulates which standards have to be met by a new watch. The
level of waterproofness is given in atm and noted on the base of the ca-
sing. Your DETOMASO watch has been tested and has a water resistance
of 5 ATM. The specification „5 ATM" is not to be confused with the diving
depth; it is simply the definition of the inspection pressure. An inspection
pressure of 5 ATM is reached at a depth of 50 m. You cannot go diving
with this watch.
In some cases a short-term higher pressure than the guaranteed inspec-
tion pressure may be enforced on the seals, for example when swimming
or diving into water. Watches are at particular risk when the wearer dives
into water after sunbathing. The combination of the impact pressure with
the negative pressure caused by the sudden drop in temperature can qui-
te easily cause damage. It is important to check and, if necessary, replace
seals when the battery is replaced.
