Audemars Piguet Code 11.59 White Gold — Black Dial with Diamond Hour Markers | Ref. 26393BC.OO.A002KB.02

Among Code 11.59 Chronograph references, the 26393BC with its diamond-set hour markers and jet black lacquered dial represents Audemars Piguet's most opulent expression of the collection's bi-curved case architecture. The 18-carat white gold case — encompassing the case middle, bezel, lugs and caseback — glows against the deep black dial, whose diamond hour markers scatter light in a manner no applied metal index could replicate. Double glareproofed sapphire crystal front and back maximise legibility and clarity.

Driving the chronograph complication is Calibre 4401, AP's proprietary self-winding flyback chronograph movement offering approximately 70 hours of power reserve. The column-wheel architecture and horizontal clutch ensure smooth, precise chronograph operation, while the transparent caseback displays the movement's intricate architecture in full. The dial presents the Code 11.59's characteristic tri-register layout with subsidiary seconds and date.

Completed on a rubber strap with a pin buckle and water resistant to 30 metres, this reference commands an extraordinary price that reflects its combination of white gold precious metal construction, diamond dial furniture, and the complexity of the flyback chronograph. The 26393BC is a prestige collector's piece for the enthusiast who demands the very summit of the Code 11.59 Chronograph family. Complete with box and papers.
