Animation of a seconds hand of a watch at a precise frequency with system time

Hello there !

I was wondering if any of you already faced this: with a Blueprint, is there a way to synchronize the seconds from the system with a seconds hand from a 3d watch but with a specific animation ?

What I mean is that I do not want the movement to be constant, I’d like it to be jittery, like some kind of stuttering similar to mechanical watches that goes, for example at 21 600 bph or 28 800 bph. I believe that’s 3 and 4 Hz.
The chronograph from the Omega Speedmaster is a good example: https://www.youtube.com/watch?v=zhTpIVbRsfI

I already found a way for the hour and minute hands (as the movement is very slow, I don’t need a specific animation) but the one of for the second hands, not a clue and the few I tried did not worked well.

If any of you has a solution, I’d be really thankfull.

So thanks in advance guys ! See ya !
