(case, movement and dial) has been assembled, it 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.

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.

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
(
FOR SOME MODELS ONLY
)
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-
