How Do Digital Watches Work?
Battery Digital watches are a popular and important piece of technology that allow you to keep a portable measurer of time around with you. If you wear a digital watch, then you already know how useful it can be. Even better than traditional watches, these display numbers in an easy-to-read manner that even show in the dark. To begin to understand how these watches work, we have to start at the source of their power: the battery. Watch batteries are small, round and offer the power needed to work the watch. They are directly connected to a crystal oscillator. Crystal Oscillator A crystal oscillator is made out of quartz crystal and uses power from the watch’s battery in order to create a 60-hertz signal. Each hertz represents one oscillation per minute, which is a necessary number in order for the watch to accurately display the time. Counter The crystal oscillator sends this signal, which is known as the time base, through a counter next. This is a preprogrammed device that begins to
