Well, it's a type of watch, a very specific kind- a chronograph is well known, that's push a button, and you time something like a stopwatch. With a normal chronograph, you have to push another button to stop the chronograph hand, and to reset it to the "0" position (normally 12 oclock).
A monopusher chronograph is a bit more mechanically interesting- it uses only one button "pusher" to do everything- push to start the chronograph, push the same button to stop it, and the same one last third time to reset to the "0" position.
You wouldn't know one normally, unless you noticed the words "chronograph" on the watch dial, and saw only one pusher on the side of the watch. Basically, they are rare, and being a complication, make the watches that have them very expensive.
A quartz chronograph is a quartz wristwatch with a chronograph (stopwatch) complication (aka additional feature).
