Audemars Piguet Royal Oak Skeleton
This rare, Audemars Piguet Quantième Perpétuel Royal Oak Reference 25829TA is one of just 15 examples believed to have been introduced to the market in 1994. Its predecessor reference 25636 can easily be distinguished from reference 25829 due to the lack of a leap year indicator. The use of tantalum is rarely used in watchmaking due to its complex nature although it possess interesting properties such as being classified as ‘highly corrosion resistant’.
The Quantième Perpétuel holds a special place in the history of Audemars Piguet, some argue that the complication allowed the brand to survive the Quartz Crisis (reference 5548). Originally introduce in 1955, Audemars Piguet began production on the very first series of Quantième Perpétuel wristwatches to feature the astronomical leap year indication. This next evolution of reference 5516 was made in a total of only 9 examples. They feature meticulously finished 36.5 mm cases and beautifully detailed dials. The rather provocative Royal Oak, designed by Gerald Genta, was said to have been gaining traction towards the mid 1980’s. In 1984, the fusion of a rather elegant complication paired with the dynamic Royal Oak was formed, the all new reference 5554 (also known as 25554) was the world’s thinnest automatic Quantième Perpétuel powered by caliber 2120/2800. The non-leap-year indicator Royal Oak Quantième Perpétuel forms part of the first series, whereas the second series produced from 1995 till 2014 features a leap-year indicator. From 2015 onwards, Audemars Piguet, added the annual week complication which resulted in a thicker movement and larger case. Audemars Piguet, constantly pushed the boundaries of the Royal Oak Quantième Perpétuel , perhaps none better than this extremely rare, reference 25829TA.
Tantalum Royal Oak
This rare, tantalum and yellow gold, reference 25829TA features a sapphire transparent dial, with yellow gold indicators, darkened stick hands and blue subsidiary steel hands. The layout of the dial includes all the traditional indications of a Quantième Perpétuel: day, date, moon phase and month. The watch is signed “Audemars Piguet” on both the dial and case back.
This remarkable example measures 39mm in diameter and only 9.3mm thick, the rather sleek proportions are reminiscent of the original 5402A which retains the exact same diameter and just marginally thinner measuring 7.2mm. This particular example comes with its original bracelet and deployant clasp, featuring the hallmark of famed bracelet maker Gay Frères. The heft of the tantalum is well balanced due to the excellent craftsmanship on the bracelet, more specifically the angles at which the links (in tantalum) mesh with the yellow gold ‘bricks’ allows for ultimate comfort on the wrist.
On the reverse, the outer-case back correctly displays the unique serial number (D-82XXX), along with its case number (2X). The hallmarks are clearly defined, the watch also features its original signed crown and stainless steel Gay Frères stamped clasp. The watch is accompanied by its extract of archives dated 2017.
This Royal Oak Quantième Perpétuel is powered by the caliber 2120/2800, based off the JLC 920 found in the 5402A. The caliber 2120 was an initial project of Jaeger LeCoultre in 1967, funded by Audemars Piguet and used by several other brands.
This particular example was last serviced in 2017 by Audemars Piguet, the case and bracelet remain in immaculate condition. The watch is accompanied with an Extract of Archives dated 2017.
