Manual Winding movements

DESCRIPTION

Manual Winding movements

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.
