The new P.9000 family consists of three automatic calibers (P.9000, 9001 and 9002). All have a diameter of 13¾ lignes, two barrels that guarantee 72 hours of power reserve; a single-piece rotor, which winds in both directions thanks to an ingenious ratchet device; a balance wheel with adjustment screws, oscillating at a frequency of 4 Hertz; and a date display and stop-seconds device that allows for accurate synchronization of the hand with an external time signal. The P.9000 caliber has 195 components and is 7.9 mm thick. It is used in the new 44-mm, steel-cased Luminor 1950 Marina watches (PAM 312 and 328) and the 47-mm, titanium-cased Luminor Submersible (PAM 305).
The P.9001 caliber, with 227 components, is equipped with a GMT function, a seconds-reset device, and a power-reserve indicator, shown on the back of the watch. It powers two 44-mm, steel-cased Luminor 1950 models (PAM 320 and 329). Caliber P.9002, with 236 components, also has a GMT function. It differs from P.9001 only in the positioning of the power-reserve display. P.2002 powers the Luminor 1950 GMT Power Reserve, which uses a small hand in a circular arc on the dial to indicate the power reserve. All of the watches containing P.9000 caliber movements belong to Panerai’s Manifattura Collection of watches containing in-house movements. Sharp-eyed Paneristi will notice that for these six new models, Panerai slightly altered the design of the Luminor 1950 case. It keeps the proportions of the original, but holds a slightly less convex sapphire crystal, which barely protrudes above the bezel.
