There are four variations of the PP caliber 215:

caliber 215
caliber 215 PS
caliber 215 PS FUS 24H
caliber 215 PS LU

All are manual wind movements.

From Patek.com:

As the name implies, these movements are wound by turning the crown. The tensioned mainspring drives the wheels inside the watch as it gradually relaxes. Whether ultra thin, cut-away “skeleton”, simple or complicated, the manually wound movement is greatly appreciated by aficionados of traditional watchmaking.
