HE CASE
The Panerai Pocket Watch Tourbillon GMT Ceramica has a case of 59 mm
made of ceramic.
It perfectly blends the dual spirit of Panerai watches: the strong association
with the past and with history combined with continual research into the most
advanced technical solutions. The result is interesting both from the technical
point of view and from the purely aesthetic angle: the ceramic used is
Zirconium Oxide and it is moulded from powder using a process of isostatic
pressure (instead of being cast, as is the normal practice). In this way all the
positive features of this material are enhanced: its extreme hardness (up to five
times greater than steel), its strong resistance to a wide range of temperatures,
and the fact that when worn for long periods the watch does not become
scratched, damaged or corroded.
The case is made using manufacturing techniques involving many complex
operations which ensure a remarkable aesthetic finish and at the same time
great resistance in terms of water-resistance and shock-resistance. The case
has the characteristic cushion shape, typical of Panerai, but it retains the flat
winding crown associated with the Luminor case. The pocket watch also has
a device for attaching the chain which protects the winding crown from shocks
and accidental breakage.
The crystal is of sapphire, formed of corundum, a very hard material (second
only to diamond), free of impurities, transparent, resistant to abrasion, and
with double anti-reflective treatment.
The ceramic back has a sapphire crystal window, enabling the mechanism
and the haute horlogerie finish to be admired.
On the back of the case are engraved the case number, the sequential number
of the watch with the number produced, the material 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 3 bar, which corresponds to the

HE HISTORY OF TOURBILLON
The Tourbillon is undoubtedly one of the most fascinating inventions in
mechanics applied to watchmaking. Its birth is to be attributed to Abraham-
Louis Breguet, who designed it in 1795 and patented it in 1801.
This device was invented with the purpose of eliminating errors in rate (that is,
faster or slower deviations in the indication of time) caused by changes in the
effect of gravity on the balance, imperfections of workmanship, thickening of
lubricating oil and the consequent varying friction in the different positions of
the watch. To make it, Breguet constructed a cage containing the balance,
escapement and relative pivots which itself rotates continuously. In this way
any variation in rate which may occur when the balance is located in a
particular position will be cancelled out when the balance is in the opposite
position. For over two centuries the tourbillon has been synonymous with
extreme constructional difficulty, demanding the greatest precision in
manufacture, and for only a few years it has been used in wristwatches which
are inevitably of the highest quality. The tourbillon escapement has fascinated
generations of enthusiasts and it has always been recognised as a substantial
technical challenge. Officine Panerai has taken up this challenge and it has
even managed to make innovations in a horological speciality which has been
substantially unchanged since it was first invented.
