Catalogue Essay
The Royal Oak, designed in collaboration with Gerard Genta, was unveiled at Audemars Piguet's booth during the 1972 Basel fair. At the time, it was the most expensive sports watch to be cased in stainless steel. This daring move shocked the watchmaking community, and sparked debate on the practicality, value and aesthetics of the watch. Yet, the Royal Oak came to redefine the luxury sports watch industry, and inspired many watchmakers thereafter to create high end stainless steel wristwatches.
The present 'C series' watch, cased in stainless steel and yellow gold, features the perpetual calendar function. While the dial does not display a leap year indication, the watch automatically corrects itself every year. The watch is fitted with the ultra thin caliber 2120, giving the watch a very elegant look. Preserved in excellent condition, the present watch is truly an important member of the Royal Oak's history.
