Audemars Piguet - Royal Oak Perpetual Calendar

The Royal Oak Perpetual Calendar in 18ct pink gold is one of the purest expressions of Gérald Genta's iconic 1972 design — a dress complication housed in a sports watch silhouette. Reference 26574OR brings the perpetual calendar into the warm register of pink gold, with every link of the integrated bracelet flowing seamlessly from the octagonal case in a single, unbroken architectural statement.

The 41mm case is finished with the alternating brushed and polished surfaces that have defined the Royal Oak for half a century, the eight hexagonal screws sitting flush against the bezel. The navy "Grande Tapisserie" dial is a study in depth — the pyramid-pattern guilloché catching the light differently with every tilt of the wrist, framing the four sub-dials of the perpetual calendar layout: day, date with moonphase, month with leap-year indicator, and the unusual week-of-the-year register around the periphery. Pink gold applied hour markers and matching hands provide a quiet luminous glow.

Inside, the self-winding calibre 5134 drives the perpetual mechanism — a movement engineered to require no manual correction until the year 2100. Visible through the sapphire caseback, it carries the hand-finished bridges, polished bevels and circular Côtes de Genève that define Audemars Piguet's haute horlogerie. Supplied unworn with its original box and papers.
