The P.9001 calibre, 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; a seconds reset device which resets the seconds hand, enabling the watch to be synchronized perfectly with a reference time signal. To house this movement, a specially made version of the Luminor 1950 case has been designed, keeping the proportions of the original but featuring a slightly less convex sapphire crystal which only barely protrudes from the bezel.
The P.9001 is a variant of the P.9000 automatic calibre with several additional features: GMT, or rather a second time zone, indicated by a central hand, seconds reset and power reserve indicator on the case back.
