Chronograph watches are timepieces that feature additional stopwatch functionality in addition to telling time. They have one or more sub-dials on the main dial that allow the wearer to measure elapsed time with precision.
Chronograph watches typically have pushers on the side of the case that start, stop, and reset the stopwatch function. The sub-dials can measure seconds, minutes, and hours, depending on the complexity of the chronograph mechanism. Some chronograph watches also have a tachymeter scale on the bezel, which allows the wearer to calculate speed based on elapsed time.
Chronograph watches are popular for their sporty and functional look, and they are often associated with racing, aviation, and other high-performance activities. They can also be used for everyday wear, as many modern chronograph watches feature elegant designs that blend sportiness with classic style.
