AUDEMARS PIGUET – ROYAL OAK RD#2


THE PERPETUAL QUEST FOR FINESSE

Redesigning a calibre’s design for extra slimness. This is the challenge successfully taken up by Audemars Piguet with the thinnest perpetual calendar in the world.

Audemars Piguet has opened a new chapter in the history of Royal Oak. Introduced at the Salon International de la Haute Horlogerie in Geneva, the Royal Oak RD#2 is a prototype promising a great future for the flagship collection made by the manufacture from the Vallée de Joux. The watch includes all the aesthetic elements of the original model, dating from 1972, such as the hexagonal bezel and the famous “tapestry” pattern on the blue dial, but stands out through its slimness, since the Royal Oak RD#2 is quite simply the world’s thinnest self-winding watch with a perpetual calendar. The calibre is 2.89mm thick, while the case measures 6.30mm – almost 2mm less than the Royal Oak Extra-Thin Jumbo (8.10mm for the case, 3.05mm for the calibre)! This extreme finesse makes it a record-breaker in its category. To achieve this result, the traditional three-tier construction of a calibre has been redesigned and is now made up of a single level where the perpetual calendar complication, the cogs and the spiral have been perfectly fitted.

This new architecture with 256 components has no impact on the watch’s performances, however. The calibre 5133, with a balance wheel oscillating at 19,800 vibrations an hour, provides a minimum power reserve of 40 hours. Like every calibre with a perpetual calendar, it drives the hour and minute hands, but also the day, date and month on separate discs, the leap years and moon phases.

This exceptional mechanism is housed in a 41mm-wide platinum case, which is watertight down to 20 metres. It is worn with a strap made from the same material.
