A chronograph is a type of watch that combines the functions of a regular timepiece with a stopwatch. It allows users to measure elapsed time with precision, making it popular among athletes and professionals. Chronographs typically feature additional buttons to start, stop, and reset the timing function, along with sub-dials that display the measured time. These watches often have a sporty design and can be found in various styles, from casual to luxury. Many famous brands, such as Rolex and Tag Heuer, produce chronographs, showcasing their craftsmanship and technical innovation. Whether for racing, diving, or everyday use, chronographs are both functional and stylish.
