Flagship's loose movement

Hi everyone, I was wondering if others have noticed similar loose movement issue with their 2014-2 Flagship using the 340 movement?

Watch is fully original and its movement is securely attached to its spacer ring.

A lock ring keeps the movement and spacer ring assembly well in place vertically, but there's a lot of side to side horizontal movement when setting time.

You can see the wear marks around the lock ring from this side to side movement.

I think I need to ask my watchmaker to come up with some extra spacer, maybe just an O-ring between the spacer ring and the case. But like said, I was wondering if this is a common problem with this model?

Do you have the correct plexi glass with tension ring?

Hmm, that I haven't checked. I don't have stable hands due to neurological issue, so I will leave that check to my watchmaker (I only do the most basic stuff like opening cases and regulating). But thanks a lot for the idea what could be wrong.
