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
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 .
Estimate HKD 100,000-150,000 USD 12,000-18,000
