Officine Panerai P.2004

The P.2004 is Panerai's first in-house chronograph, a single-button column wheel design combining start/stop/reset in one pusher at 8 o'clock. Built on the P.2002 architecture with 8-day power reserve, GMT function, and central chronograph seconds with 30-minute counter at 3 o'clock. The column wheel ensures precise control of chronograph functions. Features separate bridges with brushed finish and chamfered edges. Updated to 30 jewels in 2018.
