Audemars Piguet Jules Audemars 25984 Grande Complication 25984PT.OO.1138PT.01

The Jules Audemars collection, named after the co-founder, was Audemars Piguet's classical round line before Code 11.59 took that role. It covers simple automatic dress watches as well as the brand's traditional complications: perpetual calendars, equations of time, minute repeaters and tourbillons.

Many models use the ultra-thin automatic caliber 2120 or versions of it, such as the 2120/2802 and 2120/2808 with calendar modules. Cases are mostly in pink, white or yellow gold or platinum, on leather straps. Dealers describe these pieces by full reference, which identifies the metal and dial, and check for the original box and papers, since complicated versions are often valued on completeness and service history.
