Audemars Piguet Royal Oak Perpetual Calendar 25654BA 18K Yellow Gold Men's Watch with White Dial - Luxury Dress Watch for Business & Formal Occasions

The Audemars Piguet 25654BA is a legendary vintage timepiece that blends the iconic design of the Royal Oak with the complexity of a perpetual calendar. Crafted in 18k yellow gold, its 39mm case retains the signature Gerald Genta-designed octagonal bezel, secured by exposed white gold screws. The integrated yellow gold bracelet enhances its timeless aesthetic, making it one of the most sought-after vintage Royal Oak references.

The perpetual calendar complication displays the day, date, month, moon phase, and leap year cycle, requiring no manual adjustment for irregular months or leap years. Powered by the ultra-thin Caliber 2120/2800, this self-winding movement exemplifies Audemars Piguet’s mastery of high complications. As one of the earliest Royal Oak Perpetual Calendar models, the 25654BA holds a special place in watchmaking history, cherished by collectors for its exquisite craftsmanship, vintage charm, and enduring prestige.
