Clock motors determine the performance and actions of the wrist watch, including fundamental timekeeping. Today's clock motors (likewise called ''movements'') are powered electronically, with a quartz crystal acting as the timing source, its high-frequency vibrations emitting a pulse train, the count of which being proportional to elapsed time. This contemporary way of timekeeping has the very same look of older mechanical clocks, but its operation is set into software program, permitting a wider variety of features than before.
