Legendary watch designer Gérald Genta received an urgent call at 4:00 PM from Audemars Piguet’s managing director demanding an unprecedented steel luxury sports watch by the next morning. Drawing inspiration from a traditional deep-sea diving helmet, Genta sketched the iconic octagonal, screw-accented design overnight.
On the eve of the 1970 Basel Fair, Audemars Piguet managing director Georges Golay gave Gérald Genta one of the most consequential rush jobs in watchmaking history. At approximately 4:00 PM, Golay called the legendary designer and asked for something audacious: a steel sports watch unlike anything that had existed before. There was one catch—he wanted the design by the following morning. Genta went to his drawing board and, in a single night, produced the basic form of what would become the Audemars Piguet Royal Oak.

The request itself reflected changing tastes. Three distributors working with Audemars Piguet had identified demand for a watch that could somehow combine sportiness, elegance and stainless steel at a level normally associated with precious-metal luxury watches. This was a radical proposition around 1970. Instead of treating steel merely as a practical material, the eventual Royal Oak would treat it almost like precious metal, using exceptionally elaborate finishing to turn the case and bracelet into part of the luxury proposition.

Genta found his inspiration in an unusual childhood memory. He recalled watching a diver being fitted with a traditional diving helmet near Geneva’s Pont de la Machine. The helmet’s bolts and protective rubber seal had fascinated him because the diver’s life literally depended upon that construction remaining watertight. When Golay asked for the unprecedented sports watch, that memory returned. Genta translated the industrial language of the diving helmet into an octagonal bezel, eight visible fasteners and a visible gasket. AP Chronicles
And Genta didn’t stop with the bezel. His overnight drawing already contained many of the elements that would define the finished Royal Oak: the dramatic case, integrated bracelet with tapering links, blue patterned dial and exposed construction details. AP’s archive identifies the surviving original as a gouache-and-pencil drawing on card, produced during the night of April 10–11, 1970. The remarkable thing isn’t merely that Genta produced a rough concept overnight—the essential visual DNA of the Royal Oak was already there. AP Chronicles
But the Royal Oak wasn’t immediately ready for customers. Turning Genta’s sketch into an actual watch proved enormously challenging, particularly because of the complicated steel case and integrated bracelet. Case makers were sufficiently concerned about manufacturing the design that early development work involved more malleable gold before the final steel execution. The bracelet itself became an extraordinary manufacturing challenge, with differently sized components required to achieve its distinctive taper. AP Chronicles
After roughly two years of development, the finished Royal Oak finally made its official debut at the Basel Fair on April 15, 1972. The original Reference 5402 measured approximately 39 mm—large enough for the era to acquire the famous “Jumbo” nickname—and combined its radical exterior with the ultra-thin automatic Calibre 2121. AP describes the launch as genuinely polarizing: some observers were shocked by the unconventional watch, while others immediately recognized its appeal. AP Chronicles
The gamble ultimately changed the vocabulary of luxury watch design. Instead of hiding screws, seams and structural elements, the Royal Oak celebrated them. Instead of disguising stainless steel as something more precious, it demonstrated that steel itself could become luxurious through design and finishing. And instead of separating an elegant watch from a sports watch, Genta created an object intended to inhabit both worlds. More than five decades later, Audemars Piguet still describes those lines—sketched in one night—as the foundation of a recognizable design language that has endured for generations. Audemars Piguet
✏️ Did You Know?
There’s an especially wonderful twist in Genta’s recollection: he said he actually misunderstood Golay’s brief. Genta thought he had heard a request for a steel sports watch with unprecedented water resistance, which helped trigger his memory of the diving helmet. That apparent misunderstanding contributed to the exposed gasket, eight fasteners and industrial architecture that became some of the most recognizable details in modern watchmaking.
