A chronograph watch is a timepiece equipped with a built-in stopwatch function, allowing the wearer to measure elapsed time independently from standard timekeeping using pushers and subdials.

The chronograph is activated through pushers that engage a series of mechanical components, enabling the user to start, stop, and reset the timing function without interrupting the main movement.

A standard watch displays time only, while a chronograph adds timing capabilities, often featuring multiple subdials to track seconds, minutes, and hours of elapsed time.

A flyback chronograph allows the user to reset and restart the timing function instantly with a single push, rather than stopping, resetting, and starting again in separate steps.

Yes, chronograph watches are significantly more complex due to the additional mechanisms required to control the stopwatch function, making them more intricate to design, assemble, and service.
