A stopwatch is a handheld timepiece designed to measure the amount of elapsed time from a specific starting point to the moment the device is deactivated. Unlike a standard clock that displays the current time of day, a stopwatch focuses entirely on tracking precise time intervals. They are widely used in athletic track events, swimming races, laboratory experiments, and industrial time studies. Types of Stopwatches
Digital: The most common modern variety, powered by lithium batteries and regulated by internal quartz crystals. They show time numerically on an LCD display and can track time down to 1/100th or even 1/1000th of a second.
Mechanical: Traditional analog devices powered by an internal spring mechanism that requires manual winding. They feature physical sweeping hands and a circular dial, typically measuring intervals with a precision of 0.1 seconds.
Software: Virtual stopwatches built directly into modern consumer technology, including smartphone apps, smartwatches, and desktop operating systems. Core Functions & Button Layout
