The Audemars Piguet Royal Oak Chronograph "City of Sails" (reference: 25979ST.OO.D002CA.01 or 25979ST.OO.0002CA.01) is an iconic, highly collectible limited-edition timepiece.

Released in 2002 with a limited run of 1,250 pieces worldwide, it was created to celebrate the 30th anniversary of the Royal Oak and to honor the Swiss sailing team Alinghi ahead of their victory in the 2003 America's Cup. This model holds historic significance for the brand, as it was the first Royal Oak to be factory-equipped with a rubber strap, bringing a distinct regatta and sporty character to its stainless steel case.
