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.

ESTS CARRIED OUT ON THE ROTATING BEZEL
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.

ATER RESISTANCE TEST ISO 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.

HE WINDING CROWN SHOCK RESISTANCE TEST
The test carried out on the winding crown consists of subjecting the crown itself
to the shock of falling from a height of 50 cm, with the watch inclined at an angle
of 45°, thus unequivocally exposing this component to shocks. The crown must

maintain its water-resistance in spite of the repeated shocks it undergoes.
R
ESISTANCE TEST OF THE DEVICE PROTECTING THE WINDING CROWN
This test is performed by carrying out a series of 5,000 opening and closing
cycles of the lever of the device protecting the winding crown. The test
enables the amount of wear of the pivot of the lever and of the surface of the
winding crown in contact with the lever to be checked, ensuring maximum
reliability when the device protecting the winding crown is operated.
W
EAR RESISTANCE TEST
This test is carried out by a series of cycles in which the crown is rotated in
both directions (3,000 cycles) with a perpendicular force of 5N. The test is
equivalent to the wear which a hand-wound watch undergoes in the course of
3 years of continuous use.
F
UNCTIONAL TESTING OF THE TONGUE BUCKLE
The components of the buckle are subjected to tests against corrosion in
various climatic situations to avoid the risk of the buckle failing to operate
under any conditions of use, as well as traction tests to check the strength of
the bar connecting the buckle to the strap.
T
HE PANERAI STRAP
The strap is hypo-allergenic. Before going into production, samples of the
straps are subjected to a series of extreme actions, by simulators which
imitate the conditions of use over a period of several years. Tests include
resistance to traction, twisting (to check the relationship between stiffness and
flexibility), abrasion (friction against rough surfaces measures the resistance of
the strap and its colour), sweat (seven-day test carried out by rubbing the
sample with a felt tip soaked in a strongly acid chemical solution), humidity
and UV rays.
