8 DAYS. THE DNA OF PANERAI.
"The winding crown is one of the elements most exposed to strains, manipulation and, consequently, wear. The length of the power reserve and the consequent regularity with which a watch must be wound are therefore crucial elements for its proper functioning, particularly for a professional instrument designed for ultimate reliability and accuracy.
AISI 316L STAINLESS STEEL
"AISI 316L 1.4435 stainless steel is Officine Panerai’s material par excellence since it is highly resistant to corrosion and is hypoallergenic, making it ideal for contact with the skin. The Panerai watches created for the Italian Navy were made of austenitic stainless steel, a reliable material that was also resistant to the extreme environmental conditions in which the commandos operated."
A power reserve of eight days and hand-wound: the P.5000 calibre combines these two characteristics which are part of the history of Panerai watches since the first models created for the commandos of the Italian Navy. With a diameter of 15½ lignes (35.1 mm) and a thickness of 4.5 mm, the P.5000 calibre has 21 jewels, it is made up of 127 component parts and its balance wheel oscillates at a frequency of 3 Hz, equivalent to 21,600 vibrations/hour. Its original, very strong structure recalls that of old movements in which the mechanism was contained between two plates concealing most of the wheels and allowing only a few details to be seen, such as the balance cock and the intermediate wheel. The P.5000 calibre has a variable inertia balance, its period of oscillation being adjusted by turning the little timing screws on the outside of the balance wheel. Using this system the balance spring is free, without the curb pins which would otherwise be used to modify its active length. The bridge supporting the balance is fixed by two screws beneath which are threaded rings which turn in both directions, the purpose of which is to adjust the endshake of the balance staff pivots. This technical solution helps the escapement to continue running perfectly in the event of shocks.Discover calibre
Panerai watches are produced to very high standards of quality. It is worth remembering that the mechanical parts run 24 hours a day when used, so the watch must undergo regular maintenance to ensure long life and good operation.
