How a Quartz Clock Movement Works
Bill Hammack, “The Engineer Guy” gives us an excellent and easy-to-understand explanation of how a quartz clock movement works.
Quartz clocks may seem simple on the outside, but inside they rely on the remarkable consistency of a vibrating quartz crystal. When electrically stimulated, the crystal oscillates at a precise frequency (typically 32,768 times per second). An integrated circuit divides this frequency down to one pulse per second, which drives a small stepper motor and advances the hands of the clock.
In this video, Bill walks through the inner workings of a quartz movement and shows how electrical oscillation is translated into mechanical motion.
Quartz technology revolutionized timekeeping in the 20th century, making highly accurate clocks affordable and accessible worldwide.
