Characteristics

With a diameter of 13 3/4 lignes and 329 parts, the P.2002/E calibre has many useful functions: the GMT function, with a central hand for the second time zone and am/pm indicator in the small seconds dial at 9 o’clock; the date with indication of the month in the counter at 3 o’clock;a power reserve of over eight days, provided by the three springs barrels, with indication of the time remaining on the back; the mechanism which stops the balance wheel and sets the seconds hand to zero for accurately synchronizing the watch with a reference time signal; and the device for changing the hour hand quickly without interfering with the running of the watch. But the difference between the P.2002/E and the P.2002 basic version is the equation of time, that is, the measurement of the difference between actual time and the conventional time used in everyday life. It is a classic complication of Haute Horlogerie, which harks back to the ancient link between time measurement and astronomy.
