Spring Drives are pretty rare outside of Japan. Most mechanical watches today tick 8 times a second. On a small watch it's pretty smooth to me.

The balance wheel oscillates at 8 beats per second, but it requires 2 beats to complete a full second "tick", so most modern mechanical watches actually tick at 4 times per second.

It is 8 ticks per second. Look at this video of the hand up close (it's a 28800 bph movement):
