Further Details
The Jules Audemars Equation of Time was introduced into the market in 2000 and incorporates a perpetual calendar with leap year indicator. This complicated wristwatch mechanically tracks the time of sunrise and sunset for the designated city indicated on the on bezel, in this case the home of Audemars Piguet in Le Brassus, and accurately shows the difference between mean solar time and sidereal time. The Equation of Time and its 423 components is another example for Audemars Piguet's dedication to the art of fine watchmaking.
The equation of time is the difference between true solar time and mean time: true solar time, given by sundials, varies from day to day because of the Earth's elliptical orbit, and according to the longitude of the point of observation. Mean time, given by watches, ignores these variations and for every day of the year mathematically divides time into equal hours.
