About the PAM00609's P.5000 Caliber Movement:
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 15¾ lignes (35.7 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.
