What is a chronograph?Updated 7 months ago

A chronograph is basically a stopwatch with which you can measure a certain period of time. These watches have a button above and below the crown where you can start and stop the time.

The top button is used to start and stop the time, and the lower button is used to reset the time. If the hand is not exactly at zero, or you want to start from a different position, you can set the second hand manually. To do this, pull the crown out of the case once or twice until the time stops completely. Then you can adjust the hand with the top button.
