Audemars Piguet Royal Oak Quantième Perpétuel 18K – Ref. 25657BA. Elegant 36mm Audemars Piguet crafted in 18-carat yellow gold. Only 1,309 pieces of this reference were produced in yellow gold between 1982 and 1993. The ref. 25657 was made with several different dial configurations—this white version is the most understated of them all, featuring refined applied hour markers in 18k yellow gold and matching slim gold hands. This sophisticated Royal Oak houses a highly complicated perpetual calendar, along with a classic moonphase display. Powered by the automatic Caliber 2120/2800. The watch only comes with service pouch.
