Audemars Piguet Royal Oak Perpetual Calendar 26579CB.OO.1225CB.01 White Ceramic Blue Dial (2019)

The Royal Oak Perpetual Calendar in white ceramic represents one of the most technically demanding executions in Audemars Piguet's catalog. For collectors, the reference unites Gérald Genta's defining 1972 design with one of horology's most revered complications, rendered in a luminous white ceramic that has become among the most coveted and difficult-to-acquire expressions of the modern Royal Oak.

The 41mm case in hand-finished white ceramic measures 9.5mm thick, framing a blue "Grande Tapisserie" dial with silver-toned counters, white gold applied hour markers, and a blue inner bezel bearing the week indicator. The perpetual calendar displays day at nine, date at three, month and leap year at twelve, and astronomical moon phase at six. The self-winding Caliber 5134, derived from the ultra-thin 2120 of the original Royal Oak, delivers a 40-hour power reserve and is visible through the sapphire caseback. A full white ceramic Royal Oak bracelet with titanium folding clasp completes the watch.
