Automatic quartz is a collective term describing watch movements that combine a self-winding rotor mechanism[1] (as used in automatic mechanical watches) to generate electricity with a piezoelectric quartz crystal as its timing element. Such movements aim to provide the advantages of quartz without the inconvenience and environmental impact of batteries. Several manufacturers employ this technique.
