The ‘Royal Oak’ overturned the prevailing codes in 1972 during a period of existential crisis for the watch industry due to the boom of the cheap Quartz watches made in Asia. The company had to come with a bold, solid stainless sports steel luxury watch, they gave the mission to Gerald Genta to design it.
He got the inspiration from a deep-sea-diving helmet, the result was an octagonal bezel, visible mounting screws, a large case of 39mm with an integrated bracelet, a very futuristic design for the seventies.

Within 2-3 years they sold about 1000 watches establishing a new segment within the industry and pioneered the popularity and desirability of the steel sports luxury watch.

The first model released was the reference 5402 known today as the “Royal Oak A series”, with a thin automatic calibre 2121 movement that is still made today.
Since they treated steel as gold, the level of finishing was remarkable and so was the retail price, for comparison purpose a similar Rolex sport watch was 10x cheaper.
Today, Audemars Piguet still produces a range of Royal Oaks in different sizes (33 to 41mm) for ladies and men, from titanium, rose gold, yellow gold and platinum metals, various dial colours and with different complications.
