is tested again using various instruments to ensure the perfect water-
resistance of your watch.
Moreover, the case undergoes: the thermal shock test to verify the resistance
of the parts to sudden temperature variations; the damp heat test to determine
the reliability of the watch under dampness and heat conditions; the salt spray
test to check the corrosion resistance, and the synthetic sweat test to verify
possible alterations by artificially simulating the conditions of use.
T
ESTS CARRIED OUT ON THE ROTATING BEZEL
(
ONLY FOR THE SUBMERSIBLE MODELS
)
The rotating bezel is submitted to two tests: a rotation test of 6,000 turns at a
rate of 6 turns per minute with torque controls, and a sand-resistance test.
This cycle of tests is equivalent to the watch being used for about five years
under average conditions.

RESISTANCE TEST
(
ISO
22810
STANDARD
)
The case of the watch is subjected to a long series of tests, carried out at
various temperatures and according to procedures which ensure its complete
water-resistance. To simulate the effects which could occur in the event of the
watch being exposed to a shower or immersed in water for a long time, the
case is initially tested by a vacuum apparatus, then it is placed in a little bath
with a few centimetres of water for a set period of time. The water-resistance
test is carried out by a special instrument which subjects the watch to a
pressure significantly greater than the guaranteed value of water-resistance.
Finally, the strict Panerai standards provide for a “water drop” test, which is
performed by heating the case and placing a drop of cold water or a cold
external element on the surface of the crystal protecting the dial. In this way,
the possibility that there might be any moisture inside the case itself is
eliminated.

A
GEING TEST OF THE HAND
-
SETTING MECHANISM AND WINDING STEM
This test is performed by carrying out a series of 1,000 cycles on the winding
stem and the hand-setting mechanism, followed by a resistance test of the
winding stem subjected to a force of 25N.
A
GEING TEST OF THE AUTOMATIC WINDING MECHANISM
This test is carried out on the automatic winding mechanism over 3,000 hours,
which is equivalent to the use of the watch for about 5 years.
A
GEING TEST OF THE MANUAL WINDING MECHANISM
This test is carried out on the manual winding mechanism over 260 cycles of
one week each, which is equivalent to the use of the watch for about 5 years.
A
NTIMAGNETIC WATCH
(
ISO
764
STANDARD
)
In the presence of magnetic fields with an intensity of 4,800 A/m - 40,000 A/m
for the Amagnetic models - the watch must continue to run regularly.
T
HE CASE
The materials used in the construction of the case provide freedom from
almost all allergic reactions. Please note that each person may have a natural
predisposition to allergy to materials that are considered to be hypo-allergenic.
T
ESTS CARRIED OUT ON THE CASE
The quality of every single component of the case is checked. Then, after the
case has been assembled, it undergoes its first test for water-resistance, to
guarantee the protection it provides against the infiltration of dust and
humidity. When the watch (case, movement and dial) has been assembled, it
