THE L’ASTRONOMO - LUMINOR 1950

TOURBILLON EQUATION OF TIME WATCH

Dedicated  to  the  admirers  of  great  technical  complications  and  produced
according  to  the  customer’s  specific  requests,  the  L’Astronomo  -  Luminor
1950 Tourbillon Equation of Time by Officine Panerai is a tribute to the genius
of Galileo Galilei.
The watch functions are immediately evident and clearly displayed on the dial:
a date window at 3 o’clock, alongside the small dial with the month indicator,
the  sunrise  and  sunset  times,  the  equation  of  time  display  and  the  small
seconds dial with tourbillon indicator at 9 o’clock.
The P.2005/G calibre features a typical Panerai tourbillon regulator, which can
be  admired  through  the  back.  The  special  feature  of  the  regulating  device
developed by Panerai lies in the fact that the Tourbillon cage rotates on an axis
at right angles to the axis of the balance wheel

(diagram a)

and that it makes

two rotations per minute: this rotation ensures great accuracy, providing the

best compensation for the irregular rate caused by the effect of the force of
gravity. The fascinating motion of the tourbillon

(P)

can be admired both

through the back of the watch and on the small seconds dial, where the tiny
rotating disc of the tourbillon indicator

(K)

rotates twice as quickly as the

seconds hand, since it moves at the speed of the tourbillon cage.
A further hugely fascinating element enhances the sophistication and
uniqueness of the watch: the map of the sky which, day by day, reflects the
same portion of the night sky that is visible from the city chosen by the owner.
Engraved on the P.2005/G movement are the individual sequential number of
the movement and the name of the city; this name is also engraved on the
back of the case, together with the geographical coordinates of the specific
address chosen by the customer.

HE CASE

The case of the Panerai L’Astronomo - Luminor 1950 Tourbillon Equation of Time
is 50mm in diameter. 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 shock absorption.
To  optimise  the  reliability  of  the  watch  over  a  long  period,  the  winding  crown
incorporates a special element with a threaded ring. Its 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 on the bridge fixed to the case, which is engraved with the letters REG.
T.M. (registered trademark). The lever is terminated by a small rotating cushion-
like component, which prevents wear to 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 synthetic sapphire, obtained from corundum, a very hard
material  (second  only  to  diamond),  free  of  impurities,  transparent,  resistant  to
abrasion and with anti-reflective treatment.
The  screw-in  back  has  a  sapphire  crystal  window,  enabling  the  mechanism
