What is a Chronograph?

So have you ever asked this question, what exactly is a Chronograph watch?

It may seem like a really absurd question to most people who know a thing or two about watches.

But guess what, I have been asked this question before. So why not explain it?

Firstly, before I carry on, yes I do know there are a ton of websites and books out there that already explain or give you the answer you are looking for with regards to “what is chronograph or tachymeter” and so on. Well yes it is true, there are so why exactly am I writing then?

I am doing this to help myself further understand and learn from what already little or much I may know. As you can never know too much.

Similarly I do live by the principle of, "We learn new things everyday". So writing helps me to learn and express. 

Carrying on, so the most basic kind of watches out there are the ones that only show you the time. It has numerals (most of the time, some omit numerals altogether) and 3 hands (Hour, Minute and Second) like shown below.

Some basic watches do have other patterns or designs, like the Nomos Tangente, which right now is one of my favourite pieces out there. This particular model has a separate second hand counter. ( On a side note, this is such a lovely and classic piece that I would really like to own, soon)

Before I carry on, we owe it all to Monsieur Louis Moinet, the inventor of Chronograph. So the back story was that in those days the "aristocrats" were interested in the cosmos, so this invention was actually used for tracking astronomical objects.

In essence, chronograph watch is basically a watch that has a stopwatch function added into it. Chronograph watches can be either automatic or quartz and feature various complications at once and have several sub dials to read off the measurements. The most basic chronograph has a separate or independent sweep second hand which can start and stop, and return to zero. There can be up to four dials on the face to indicate hour, minute, seconds and 24 hour indicator(some dials show even up to a tenth of a second), like the  Eberhard And Co. Chrono 4 Grande Taille 31052.1 shown below.

Majority of the chronograph's  features works by pushing a start button. Usually most of the start buttons are placed at the Two O Clock position to get the timer moving to record time and by pressing the same button to stop the time recording and returning to zero by pressing it over.

Each individual function of the chronograph is independent of each other. What this means is that your timepiece can tell the time and function as a stop watch concurrently.

Not to be confused, Chronograph is known as a complication of a timepiece and not its movement (of the watch).

Just to add in some technical stuff, there are 2 kinds of chronographs the automatic and digital. Difference being, automatic chronograph depends only on kinetic energy as a source of its power. The digital on the other hand works very much like a common hand help stopwatch and is run by batteries.
