Digital watches are timekeeping devices that display the time using digits rather than traditional hands. They often feature an electronic display, which can show not only the time but also additional information like the date, alarms, and timers. Many digital watches are powered by batteries and can include various functions such as stopwatches and backlighting for visibility in low light. These watches have become popular since their introduction in the 1970s, with brands like Casio and Timex leading the market. Digital watches are favored for their accuracy and ease of reading, making them suitable for everyday wear and specific activities like sports and fitness.
