With Patek Philippe Extract from the Archives confirming production of the present watch in platinum in 1963 and its subsequent sale on 21 August 1963.
In production from 1938 to 1972, reference 570 is considered a cornerstone of any serious Patek Philippe collection. Available in the three gold colors as well as in steel and in platinum, it was available with or without sweep centre seconds.
Platinum sweep centre seconds examples are exceedingly rare: in depth research indicates that most probably only eight such watches have appeared in public to date. Fresh to the market, the present example is made even more interesting by the fact that its dial features both hard-enamel Patek Philippe signature and the "sigma swiss sigma" designation: Patek Philippe introduced sigma dials approximately at the moment hard enameling of the scales was discontinued. The overlapping of these two traits happened only for the very first sigma dials, which are the very last hard-enameled dials, and is an exceedingly rare occurrence.
Models with sweep centre seconds were, at the launch of the reference, powered by 12 SCi, which was a normal calibre with subsidiary seconds modified with a hack to allow for constant seconds (SCi stands for Seconde au Centre indirecte). Subsequently, the celebrated calibre 27SC, the one at the heart of the present timepiece, is used.
