Panerai Luminor 1950 Instructions Manual page 13

The finishing of the ceramic components is done by sandblasting, a special
technique by which micro beads are blasted onto the material in order to give
it a matt finish.
In the case construction, Panerai has made use of techniques involving many
complex working operations which ensure an exceptional aesthetic finish and
the best resistance in terms of shock absorption. 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 damage as well as
helping to ensure the water-resistance of the case.
The moving lever is mounted in the bridge fixed to the case which is engraved
with the letters REG. T.M. (Registered trademark).
The crystal is made of sapphire, obtained from corundum, a very hard material
(second in hardness only to diamond), free of impurities, transparent, abrasion
resistant, and with anti-reflective treatment.
The screw-in back has a sapphire crystal window enabling the mechanism and
the haute horlogerie finish to be admired. Engraved on the titanium backcase
with hard black coating are the case number, the sequential number of the
watch with the number of the production, the materials and the maximum
depth of use.
The water-resistance of your watch, indicated on the back by the symbol
, is guaranteed to a pressure of 10 bar, which corresponds to the
hydrostatic pressure exerted by a column of water on 1 square centimetre at
a depth of 100 metres under normal conditions. In these circumstances your
watch is therefore water-resistant to a depth of about 100 metres.

HE DIAL
The dial is the characteristic Panerai "sandwich" type consisting of two
superimposed plates, the upper with perforated numerals and hour markers,
22
while the lower one is covered with a layer of luminous material.
In order to ensure optimal levels of luminescence and greater resistance over
time, Panerai uses exclusively "Grade A" Swiss Super-LumiNova
this luminous substance, special high-performance pigments are used. This
allows an increase in the duration of the readability of approximately 35%
compared to standard Super-LumiNova
The small seconds and tourbillon indicator are at 9 o'clock, the second time zone
is indicated by the central hand and by the small 24-hour dial at 3 o'clock.

HE STRAP
The leather strap is hypo-allergenic. It is fitted with an adjustable steel buckle
with hard black coating personalized Panerai.

HE MOVEMENT
Hand-wound mechanical, Panerai calibre P.2005/B, completely created by
Panerai, diameter 16¼ lignes, thickness 9.1 mm, 31 jewels, power reserve 6
days, 3 spring barrels in series, Glucydur
(equivalent to 4 Hz). KIF Parechoc
Functions: hours, minutes, seconds, second time zone, 24h indicator, power
reserve indicator visible on the back, tourbillon.
The P.2005/B movement features a special galvanic treatment that gives its
surfaces a completely black appearance. This detail contributes to the
extraordinary aesthetic impact.
The black colouration is achieved by electroplating. The thickness of the black
coating is on average two microns, which ensures that the coating does not
interfere with the working of the movement.
