Perpetual Calendar | 25657PT | Platinum curved-end with only light superficial marksFirst launched in 1978, the Quantime Perptuel by Audemars Piguet was the worlds thinnest automatic perpetual calendar. The reference 5548 was the first reference of this newly released perpetual calendar, birthing a category of watches which has taken on many different forms. Sources note that total production for the reference 25657* stands at 1821 watches, with just 128 in platinum, making this example fairly rare and not often seen on the market.
