Designed in 1971 by Gerald Genta and launched in 1972, the Royal Oak by Audemars Piguet is oneof the most iconic model in the contemporary watchmaking industry. In 1972, Audemars Piguetintroduced the Royal Oak with a first batch of 1’000 watches called “serie A” due to the letterA engraved on their caseback. Two years later, additional series were produced under the ref.5204 with the letter A, B, C and D. This model (numbered 344) appears to have been created inbetweenseries A and B in 1976 and corresponds to the 1972 design by Gerald Genta. The casebackis only signed Royal Oak with no number. It was sold on September 3rd, 1976 to the original ownerwho consigned it for this auction. In excellent condition, this is the first time a watch from this“intermediatory series” has appeares at auction.
