AUDEMARS PIGUET, STAINLESS STEEL CHRONOGRAPH 'ROYAL OAK', REF. 26331ST

The Royal Oak collection was introduced in 1972, redefining the identity of a sports watch. With groundbreaking designs, the Royal Oak secured a discerning and informed audience and became throughout the years the emblem of the Audemars Piguet manufacture as well as a true icon within the watch community. A chronograph version was added to the classic Royal Oak line only in 1998. The first Royal Oak chronograph was powered by Cal. 2385, a slim self-winding column wheel chronograph movement based on the Frédéric Piguet 1185. This model was produced for 14 years right up until 2011.
