It is also possible for quartz clocks and watches to have their quartz crystal oscillate at a higher frequency than 32 768 (= 2 15) Hz (high frequency quartz movements [4]) and/or generate digital pulses more than once per second, to drive a stepping motor powered second hand at a higher power of 2 than once every second, [5] but the electric ...
