Rattling of bracelet between the lugs

[greg35]

I just received my first Rolex, a vintage one at that.

I have raised a few questions in a different thread.
But I didn't Attache the rattle video I had.

So it is attached herez

My question:

Is this kinda rattle normal for vintage?
I know I over rattled in the video to give you guys the impression, however, I have to only slightly move my wrist and I can hear it.

Looking for answers.thanx
