Characteristics

The hand-wound P.2004/10 calibre, entirely developed and created at the Officine Panerai Manufacture at Neuchâtel, has three barrels which give it the unusually long power reserve of eight days, a classic feature of Panerai watches since the 1940s; the running time remaining is displayed by the linear power reserve indicator on the dial. With two counters and a central seconds hand, the chronograph has a single button at eight o’clock which controls the start, stop and reset functions. It has a vertical clutch and column wheel, the latter being fully visible from the back of the movement, through the sapphire window set in the caseback. The sophisticated finish and other technical details of the movement can also be seen through the back of the watch, being exposed to view by the skeletonising of the bridges and the two barrels. The P.2004/10 calibre also has the second time zone function, with the a.m./p.m. indicator on the counter at nine o’clock, and the device that automatically resets the seconds hand to zero when the time is adjusted.
