A chronograph is a type of watch that not only tells time but also functions as a stopwatch. It features additional dials and buttons that allow the user to measure elapsed time accurately. This makes it popular among athletes and professionals who need precise timing for events or activities. The design of a chronograph often includes a main dial for standard time and smaller sub-dials for tracking seconds, minutes, and hours. Many luxury watch brands, like Rolex and Omega, create chronographs that combine style with functionality, making them sought-after accessories for both collectors and everyday users.
