The P.4002 calibre builds upon the P.4000 automatic movement, sharing its bi-directional off-center micro-rotor, 3-day power reserve via twin series-linked barrels, balance stop mechanism for precision, and a stable twin-support balance bridge. It adds a date complication, a GMT central hand for a second time zone, an am/pm indicator in the small seconds dial, and a power reserve display positioned on the dial at 5 o’clock.
