A chronograph watch is a timepiece that combines standard timekeeping with a stopwatch function. It typically features additional sub-dials or hands that measure elapsed time, allowing users to time events accurately. Chronographs are popular among athletes and professionals who need precise timing. These watches can be operated using pushers on the side of the case, which start, stop, and reset the timing function. Many luxury watch brands offer chronograph models, making them a stylish choice for both casual and formal occasions. Their versatility and functionality make them a favorite among watch enthusiasts.
