  • Catalogue Essay

    In the early 2000s Audemars Piguet was the first brand to integrate in a wristwatch not only a perpetual calendar but an equation of time (based on the wearer’s city of choice) as well as time of sunset and sunrise.

    The equation of time indicates the difference between civilian time and true solar time. For convenience a day is divided in 24 hours however due to the earth’s elliptical path around the sun as well as its tilted rotation axis a day is not exactly 24 hours and depending on the season can be longer or shorter than 24 hours.

    The equation of time hand- fitted with a miniature sun at its tip-indicates the true solar time on an inner ring graduated from – 15 minutes to + 15 minutes. Nonetheless, the mean solar culmination point depends on the wearer's exact location, on the longitude of a given place on the globe. The equation of time read-off system developed by Audemars Piguet takes account of this specific place.

    The present Jules Audemars is calibrated for Gy – in the canton of Geneva (as indicated on the inner ring) and the time of the solar zenith is indicated next to the city (here 12h36).

    Other than the traditional calendar indication, the present example also indicates the times of sunrise and sunset in the owner’s desired city indicated via two subdials at 3 and 9 o’clock.

    The equation of time mechanism and inner city ring can be easily changed by Audemars Piguet to reflect the city of choice of the new owner.
