4130 movement noise 116520

I was taking a look at a preowned 116520 yesterday at a local watch stire.. The watch in question kept good time. There didnt seem to unusual rotor noise when I moved my wrist But I noticed if I lightly tap on the crystal i could hear/feel the movement slightly vibrate inside the case. Sort of like it wasn’t completely solid. Can any owners tell me if this is normal?

The 4130 has a ball bearing mounted rotor and some folks say that they can feel and hear this type of rotor.

I'm pretty sure that stuff is solid inside.

When I picked up my SD43 from service the watchmaker told me that in addition to the watch winding down and stopping he was able to hear the movement that he explained was a no no. After injecting light oil the watch perked up and the noise was silenced. Maybe we are not supposed to hear a Rolex movement? I must admit, I never tried.
