APSF Edition — Black Calfskin Leather Strap
The Audemars Piguet Code 11.59 represents one of the most complex case architectures in modern horology, and APSF has established the definitive benchmark for the 15210OR. This edition accurately captures the intricate octagonal mid-case, seamlessly welded to the open-worked lugs and ultra-thin round bezel.
Powered by the custom AP Calibre 4302 clone movement, this piece mirrors the genuine architecture with a meticulously finished 22K pink gold-toned oscillating weight. The movement beats at a precise 28,800 vph, providing an ultra-smooth sweep, while delivering a power reserve of approximately 36 hours.
Measuring exactly 41mm in diameter and a verified 10.8mm in thickness, the 18K rose gold plated case showcases meticulous brushed and polished alternating finishing. The black lacquered dial, revealing subtle warm umber undertones under direct light, is protected by the signature double-curved sapphire crystal with anti-reflective coating.
