wtf is a chronograph?

So I bought my friend a watch as a congratulatory gift for completing his marathon this past weekend.

The watch comes with a chronograph. What the hell does that do?

:confused:

That would be fancy market-speak for a stopwatch.

are you serious? A stop watch? I fiddled with that think for half an hour and I couldn’t figure out what it did!

thanks :slight_smile:

What is the difference between a Chronometer and a Chronograph?

Isn’t a chronograph a device for accurately measuring the speeds of projectiles (specifically, bullets). They have two “panels” parallel to each through which the projectile passes. I don’t know how they work exactly*, but from this it calculates the speed.

(*aside from the obvious fact that they find the entrance time, exit time and they know the distance between those points)

Well, yes, in some circumstances it is (and I believe they work by having an optical sensor that detects the shadow of the passing bullet; the ones I’ve seen have a white 1" strip mounted above the eye' against which to see’ it). But somehow I have trouble seeing one of those as a feature on a watch, so I assume it graphs' (displays) the chronos’ (time) between pressing a start and stop button instead :slight_smile:
