Audemars Piguet Royal Oak Jumbo Extra-Thin White Gold — Grainy Blue Dial | Ref. 16202BC.OO.1240BC.02

In 1972, Gerald Genta sketched the Royal Oak on a single sheet of paper — and in doing so, permanently altered the trajectory of luxury watchmaking. The Royal Oak Jumbo Extra-Thin, reference 16202BC.OO.1240BC.02, is the purest expression of that founding vision, rendered here in 18-carat white gold with the iconic grainy blue dial. The 39 mm octagonal case, defined by its eight hexagonal screws and integrated bracelet, has remained architecturally faithful to Genta's original blueprint while evolving in material refinement. This is the reference that connoisseurs consider the Royal Oak in its most authentic, most essential form.

The movement is the celebrated Calibre 2121 — or as listed, Calibre 4302, depending on the production specification — an ultra-thin self-winding manufacture movement that sits at just 3.05 mm in height. Developed through a long-standing partnership with movement specialist Jaeger-LeCoultre, the Calibre 2121 operates at 2.75 Hz (19,800 vph) with a 40-hour power reserve, and is responsible for the Royal Oak Jumbo's trademark wafer-thin profile of just 7.8 mm. The transparent caseback reveals a movement of extraordinary finish quality, with bevelled bridges and Geneva stripes that reward the patient observer.

Luminous index markers populate the signature blue petite tapisserie dial, their cool glow a perfect foil to the cold brilliance of white gold. The integrated white gold bracelet, secured by an AP folding clasp, flows seamlessly from the case — a hallmark of Genta's integrated bracelet concept that remains the benchmark of luxury sports watch design. Water resistant to 50 metres and accompanied by box and papers, the 16202BC is the ultimate collector's Royal Oak: the white gold Jumbo is produced in limited numbers and is among the most coveted references in Audemars Piguet's contemporary catalogue, priced at $139,999.
