Panerai caliber P.9000

The P.9000 caliber, created entirely by Officine Panerai and used in a series of Luminor 1950 and Radiomir models, is fitted with various functions: it is an automatic calibre with a 3-day power reserve and a unique technical design which makes these movements immediately recognizable. The calibre has a diameter of 13¾ lignes and numerous features: two barrels which guarantee 72 hours of power reserve; a single piece rotor which winds by moving in both directions thanks to an automatic ratchet device; a balance wheel with adjusting screws, oscillating at a frequency of 4 Hz.
