How smoothly should a ETA 2834-2 movement sweeping hand move?

[cybo]

Hey guys. I recently bought my Hamilton Khaki King automatic online used and so it is probably fine (I think), I am just making sure with people more familiar with automatics and ETA movements than I. So, my question to you is this: how smoothly should the second hand sweep? On this watch it is just enough that it is not a fluid motion, almost as if it is moving 30+ times in 5 seconds or such. The movement is definitely the genuine article, so I thought I would make sure there is nothing wrong with the movement (that it isn't going to break on me!). Thanks.
