History
The Royal Oak’s journey began in 1972 when Audemars Piguet’s founder, Léon Audemars, commissioned Gérald Genta to create a luxury sports watch that would stand out from the crowd. Genta’s vision was to blend the robustness of a sports watch with the sophistication of a dress watch, and the result was a piece that challenged conventional design norms.
While the original Royal Oak debuted in 1972 with a black dial, the blue dial version was introduced in 1973. The choice of blue was deliberate: it offered a subtle contrast to the gold case and the silver or steel hands, creating a dial that was both eye-catching and timeless. Over the years, the blue dial has evolved through several iterations—most notably the 42mm 1998 model, the 39mm 2008 “Blue” edition, and the 40mm 2018 “Royal Oak Offshore” with a larger blue dial.

From the introduction of the self-winding movement to the incorporation of high-tech materials like ceramic and titanium, the blue dial has remained a benchmark for innovation while staying true to its original design ethos.
