The Royal Oak Perpetual Calendar represents Audemars Piguet at its most ambitious, embedding one of watchmaking’s complications within Gérald Genta’s sports-watch icon. This reference 25820 ranks among the coveted vintage examples, combining the robust yet refined case with a perpetual calendar. Its rarity is amplified by two choices: a platinum case and bracelet, and a salmon dial seldom encountered on the model. Together they create a collector’s piece, uniting horological gravitas with connoisseur-driven exclusivity at the highest level.

Measuring 39mm, the platinum case and integrated bracelet carry the Royal Oak’s octagonal bezel and hexagonal screws, their heft a signal of the precious metal within. The salmon dial showcases the brand’s Grande Tapisserie waffle pattern, hosting a perpetual calendar: day at nine, date at three, month with leap-year at twelve, and a moon phase above a week counter. Applied white gold markers and hands ensure clarity across the warm-toned, lustrous surface.
