A digital watch is a timepiece that displays the time in electronic digits. There are several synonyms for digital watch, including electronic watch, LED watch, quartz watch, and timepiece. An electronic watch is digital and uses a quartz crystal to keep time while an LED watch displays the time using light-emitting diodes. Quartz watches are also digital and use a quartz crystal to keep time, but they are often designed to look like traditional watches. A timepiece is another term for a watch, but it is often used to describe particularly elegant or elaborate watches. No matter what you call it, a digital watch is a reliable and convenient way to keep track of time.
