Audemars Piguet Jules Audemars Equation of Time watch

The Audemars Piguet Jules Audemars Equation of Time watch is a remarkable high luxury timepiece which shows off an innovative astronomic complication, in combination with the celebrated perpetual calendar function. Since 1875, such lofty mechanical virtuosities have been a speciality of the house of Audemars Piguet, firmly establishing the brand as a master of classical haute horlogerie.

The Audemars Piguet Jules Audemars Equation of Time watch presents a unique display of complex information. The perpetual calendar mechanism indicates day of the week, date, month, proper leap year, and phases of the moon; this complication automatically switches the date according to the various lengths of months, and accounts for changes in the month of February due to leap years. Audemars Piguet produces the Equation of Time watch to order, with cams and and a bezel that are mechanically programmed to the specific location of the client; with this done, time of sunrise and sunset in a given location are accurately displayed, as well as the equation of time---the difference between true solar time (as a sundial depicts), and mean solar time (the average represented by a 24-hour day). These two values coincide only four times annually, the rest of the year varying between anywhere from -16 to +15 minutes; thus the serpentine sun-tipped hand, indicates this mathematical difference.

Thanks to the unique calibrated bezels, which are location specific, the Audemars Piguet Jules Audemars Equation of Time watch also shows the exact time of solar culmination--the period when the sun is at its highest point. The Audemars Piguet Jules Audemars Equation of Time watch is animated by a complex and extremely refined selfwinding movement, the 2120/2808 caliber. The movement base for this watch is a haute horlogerie legend, having debuted in 1967, at which time it was the thinnest central-rotor automatic movement ever produced. Equipped with a ruby-roller borne ring which supports the rotor mass, and a unique bi-directional winding system that disengages during hand-winding to prevent additional wear, this movement still garners acclaim for its ultra-thin height, and extremely refined details. In all, the 2120/2808 caliber comprises 423 components, each of which has been refined by hand. A glance through the exhibition sapphire caseback reveals the beautiful movement, which glitters with Cotes de Geneve, anglage, and perlage decorations, as well as counter-sunk and polished jewel and screw settings. The rotor has been relieved of all excess material, to showcase the AP initials, and the intricate framework displays fine floral engravings; a massive 21K gold segment on the outer rim facilitates optimal winding motion.

The Audemars Piguet Jules Audemars Equation of Time watch is crafted exclusively in 18K pink gold, 18K white gold, or 18K yellow gold. These stunning cases, which demonstrate an intricate and sensual combination of brushed and polished finishes, characterize the Jules Audemars watch collection, and for this timepiece, measure 43mm in diameter. The beautiful dial of the Equation of Time watch, produced by Audemars Piguet in black for the pink gold watch, and silver for the yellow and white gold versions, display an intricate guilloche pattern and classical details such as Roman numerals and leaf hands wrought from solid gold. Each of these complex Audemars Piguet timepieces are complemented by a luxurious crocodile strap and an elegant 18K gold folding clasp.
