Audemars Piguet QP Platinum

Audemars Piguet reference 25668PT in platinum, produced in the 1990s within Audemars Piguet’s automatic perpetual calendar line introduced in 1978. The 36 mm platinum case features a stepped bezel and corrector pushers on the case band, housing a sapphire skeleton dial with blue rings for the day, month, and date, and a moon phase at 6 o’clock. The movement is based on the ultra-thin Jaeger-LeCoultre caliber 920, adapted by Audemars Piguet to incorporate a perpetual calendar.
