Reasons to Bid
The Audemars Piguet Royal Oak Perpetual Calendar Ref. 25654BA stands among the most coveted Perpetual Calendar Royal Oaks, representing the third generation of the complication within Gérald Genta’s iconic design lineage. The model presents a striking blend of architectural sportiness and haute horlogerie, the Royal Oak at its most luxurious. Maintaining the same case diameter as the original jumbo size at 39mm, this 18k yellow gold case comes in at only 8.3mm in thickness thanks to the ultra-slim Caliber 2120/2800, based on the legendary Jaeger-LeCoultre 920 ébauche universally regarded as one of the finest mechanical movements ever to be produced. Modified and finished to Audemars Piguet’s standards, the movement incorporates the full perpetual calendar mechanism while maintaining remarkable thinness, allowing the watch to sit elegantly on any wrist.
