What is the primary function of a chronograph in a wristwatch?

The primary function of a chronograph in a wristwatch is to measure elapsed time. A chronograph is a type of watch that includes a stopwatch feature, allowing the wearer to track time intervals accurately. This is typically achieved through the use of additional buttons on the side of the watch that start, stop, and reset the timing function, often displayed on sub-dials or an outer scale on the watch face.

In addition to its timekeeping abilities, a chronograph can have various applications, such as timing races, sports events, or even cooking. It is distinguished from a standard watch by its ability to record specific time periods while also keeping the standard time display.

Other options, such as displaying the date, showing multiple time zones, or indicating battery levels, pertain to different functionalities found in other types of watches but are not features of a chronograph. The focus of a chronograph is specifically on timing, making it particularly valued in contexts where precise time measurement is crucial.
