Audemars Piguet Quantième Perpetuel, 25657OR, Rose Gold


First launched in 1978, the Quantième Perpetuel by Audemars Piguet was the world’s thinnest automatic perpetual calendar. One of only 362 examples in rose gold, this reference 25657 captures much of the appeal of the earliest pieces, with its classic "Audemars Piguet" signature, crisp white dial, and moonphase.
