Panerai caliber P.4002

The P.4002 calibre is developed from the automatic P.4000 movement whose main technical characteristics it share: the off-centre micro rotor which rotates in both directions, the power reserve of three days stored in two spring barrels linked in series, the mechanism for stopping the balance, enabling the time to be set with absolute precision and the full balance bridge with twin supports for greater stability. The calibre also have some extremely useful additional functions: the date, the GMT function with a central hand which indicates the time in a second time zone, am/pm indication (relative to home time) in the small seconds dial and, finally, indication of the remaining power reserve positioned directly on the dial at 5 o’clock.
