Officine Panerai P.4000

The P.4000 is Panerai's first automatic movement with off-center micro-rotor, entirely developed at the Neuchâtel Manufacture. The micro-rotor design enables exceptional thinness of only 3.95mm while maintaining Panerai's signature 3-day power reserve via two spring barrels. Features tungsten alloy micro-rotor winding in both directions, twin-supported balance cock for stability, and variable inertia balance wheel. First introduced at Watches and Wonders 2014.
