What is a chronograph watch?

A chronograph watch is a timepiece with an added complication: a built-in stopwatch function. It allows the wearer to measure elapsed time independently of the watch's standard timekeeping function.

Here's a breakdown of important aspects:

• Functionality: A chronograph typically features a large central seconds hand for measuring elapsed seconds. Separate subdials (or registers) display elapsed minutes and sometimes hours.

• Operation: Pushers (buttons) on the side of the case control the chronograph's start, stop, and reset functions. Usually, one pusher starts and stops the chronograph, and another resets it. Some have flyback or split-seconds functionalities.

• Types: Chronographs can be mechanical (manual or automatic winding) or quartz. Mechanical chronographs are highly valued for their craftsmanship and complexity.

• Readability: A clear and legible dial is crucial for effectively using the chronograph function. Many chronographs have contrasting hands and scales for improved readability.

• Tachymeter: Many chronographs feature a tachymeter scale on the bezel, which can be used to measure speed over a known distance.
