THE LUMINOR SUBMERSIBLE 1950
2500m 3 DAYS AUTOMATIC TITANIO WATCH
In its long history, Officine Panerai has often been involved with the world of
the deep, creating watches capable of operating at extreme depths. With the
new Luminor Submersible 1950 2500m 3 Days Automatic Titanio, Officine
Panerai continues this long tradition, closely linked to its own history, enriching
it with new technical content to offer underwater watch enthusiasts a
professional instrument of exceptional performance.
The Luminor Submersible 1950 2500m 3 Days Automatic Titanio watch is a
special edition of 1.000 pieces.

HE CASE
The Panerai Luminor Submersible 1950 2500m 3 Days Automatic Titanio
watch has a 47 mm case made of brushed titanium.
The titanium used by Officine Panerai is light, strong and hypoallergenic: the
remarkable physical, mechanical and corrosion resistant qualities of titanium
have made this metal one of the most valued in fine watchmaking, as well as
a material of choice for the military, aeronautical and aerospace industries. It
is the most widely used and provides the best compromise between strength,
corrosion resistance, weldability and mouldability.
In the construction of the case, Panerai has made use of techniques involving
many complex working operations, which ensure an exceptional aesthetic
finish and the best resistance in terms of absorbing shocks.
To optimise the reliability of the watch over a long period, the winding crown
incorporates a special element with a threaded ring whose function is to
control the degree of force with which the winding crown is locked by the
device protecting the winding crown, which protects it from shocks and
accidental breakage and helps to ensure the water-resistance of the case.
The moving lever is mounted in the bridge fixed to the case which is engraved
20
with the letters REG. T.M. (Registered trademark). The lever is terminated by a
small rotating cushion-like component, which avoids wear at the end of the
lever in contact with the crown, allowing the most effective setting of the axial
pressure between the two parts.
The crystal is of sapphire, made of corundum, a very hard material (second
only to diamond), free of impurities, transparent, resistant to abrasion, and
with anti-reflective treatment.
The solid screw-in back is made of titanium. On the back of the case are
engraved the case number, the sequential number of the watch with the
number produced, the material, the maximum depth of use and the
designation Divers Professional.
The water-resistance of your watch, indicated on the back by the symbol
, is guaranteed to a pressure of 250 bar, which corresponds to the
hydrostatic pressure exerted by a column of water on 1 square centimetre at
a depth of 2.500 metres under normal conditions. In these circumstances your
watch is therefore water-resistant to a depth of about 2.500 metres.

HE UNIDIRECTIONAL ROTATING BEZEL
The bezel is of the unidirectional type, rotating only anti-clockwise. It has
a scale divided into 60ths, graduated in minutes for the first 15 minutes and
then every 5 minutes. The movement of the bezel when it is being set is very
distinctive. It is of radial design, using a metal ring-shaped element which
significantly improves the precision of the click, as well as ensuring that the
bezel has the greatest possible resistance to wear and to high temperatures.
Patent filed for this system of operation.

HE DIAL
The black dial has applied hour markers.
In order to ensure optimal levels of luminescence and greater resistance over
time, Panerai uses exclusively "Grade A" Swiss Super-LumiNova
