Seconds hand “jumps” every few seconds (Omega Seamaster)

Hey guys, I just noticed the seconds hand in my watch kind of jumps every few seconds. The watch also goes fast by around 3 seconds a minute, which is around 1 hour fast per day.

I bought the watch new from an Omega AD in May 2020, so it is still under warranty, which leads to my question - anyone familiar with this issue? does the 5 year warranty covers problems like the one I have?

Also, should I pull the crown out to stop the movement or just leave it as it is?

Thanks.
