About this watch

In 2022, the world celebrates the 50th anniversary of the iconic Royal Oak from Audemars Piguet. With many iterations of the Royal Oak produced since 1972 with different complications and case sizes, collectors always look for the more unique or unusual designs and models; the sort of pieces that many don’t know about or have rarely seen. Here we have the Audemars Piguet Royal Oak Quantième Annuel (French for Annual Calendar) ref. 25920ST. An annual calendar only requires adjustment once a year in February, as it accounts for the long and short months throughout the year. Briefly produced in the early 2000s, this model remains to this day the only reference from the brand to feature the annual calendar complication. Audemars Piguet decided to present this annual calendar in a compact 36mm mid-size Royal Oak design to fit the taste of the times. The dial design is also quite unique on this example and features a recessed off-centre sub-dial at the 5 o’clock position to indicate the months, while the days are indicated on a centre ring separating the dial into two distinct portions. The centre of the dial features the classic “tapisserie” motif while the outer part of the dial showcases a flat sunburst finish. Inside the watch, you will find the ultra-thin AP caliber 2225/2814, derived from Jaeger-LeCoultre’s JLC 889 calibre movement. The present example from 2005 comes with its original box, Certificate of Origin booklet and manual.

About the Brand+

Audemars Piguet

One of the most iconic names in Swiss watchmaking today, Audemars Piguet was established in 1875 by Jules-Louis Audemars and Edward-Auguste Piguet in the birthplace of Swiss watchmaking itself –the Vallée de Joux, Le Brassus. 

Audemars Piguet has cemented its 140-year legacy with an unrivalled ability to time-and-time again shatter the metaphorical horological ceiling in all facets technical and aesthetic. Its myriad of record-breaking releases over the century have, without doubt, paved the way for the era of modern horology we are so familiar with today.

A brand notorious for its bold releases, most bold of all, perhaps, was the debut of the Royal Oak in 1972 as the world’s first luxury sports watch crafted in stainless steel. The release sent shock waves throughout the watchmaking industry, but has since become the definitive blueprint of the modern steel sports watch, and its octagonal case one of the most sought after silhouettes in the world. AP’s later icons such as the Royal Oak Offshore and Concepts have further propelled the brand to new heights – not only within the watch industry, but also fostering its emergence as a 21st-century cultural icon. Today, APs transcend the world of watchmaking and double as a symbol of status and prestige, its pieces adorning the wrists of celebrities and royalty alike.
 

Despite trailblazing its way through modern Haute Horlogerie, tradition remains engrained in Audemars Piguet’s DNA -- it is the largest independent Swiss watchmaker still owned by its founding families. It is this connection that allows AP to marry its rich heritage and expertise in traditional watchmaking with ground-breaking design and craftsmanship. Each and every wristwatch boasts the manufacture’s complex savoir-faire and mastery of complications – and Audemars Piguet will no doubt continue to shift the paradigm of horology in the years to come, whether the world likes it or not.
