Why is there a free rotating hexagon head on the end of small screwdrivers (watchmaker screwdriver)?

to stabilize and put (mild) pressure on the screwbit without impairing easy turning motion

Why it is a hexagon?

Hexagon won’t roll off the table if you set it down…

Huh, of course, thanks!

My set has circles. I'd imagine whoever made your set thought hexagons looked cool and the added texture would help with grip.

Sets similar to these are everywhere, that's why I thought that there might be a reason for why it is a hexagon (other than that they are the bestagons).

I can only guess...

Makes it easy to use one-handed. Especially when you need your other hand to hold the item being worked on. Press the head against the flat or palm of your hand and use your fingers to turn the driver.

It is used as a swivel.
Grasp the barrel with the thumb and middle finger, and place the top of the index finger on the hexagon.
