Foreword
Congratulations on the purchase of your new watch. You are now the owner of a
high precision time keeper characterised by its innovative design.
We keep a long term stock of the most important spare parts for all our watches,
guaranteeing repair over a period of many years.
In order to ensure that your new watch functions properly for many years, please
read the following instructions carefully.
Waterproof Properties
The water resistance of the DETOMASO MARCO has been tested for 5 ATM. This
means that you may wash your hands or take a bath with it and that it is spraywa-
terproof. However, swimming, taking a shower or diving is not suitable.
General Information on waterproof properties
Waterproofness is not a permanent characteristic; it should be tested annually and
in particular before the watch is put under exceptional strain, as the seals deteriora-
te 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. The level of
waterproofness is given in ATM (atmosphere) and noted on the case back of the
watch. Watches are considered water resistant if they are resistant against sweat,
water droplets, rain etc. They have to remain watertight for a period of 30 minutes
when submerged in 1 m of water. These watches are for normal everyday use and
are not suitable for use in conditions where the water pressure and temperature
vary considerably.
An additional specification of pressure, such as "3 ATM", means the test conditions
have been tightened. The specification "3 ATM" is not to be confused with the diving
depth; it is simply the definition of the inspection pressure. An inspection pressure
of 3 ATM is reached at a depth of 30 meters. In some cases a short-term higher
pressure than the guaranteed inspection pressure may be enforced on the seals,
for example when swimming or diving into water.
