Blancpain

Today I noticed that the pressure valve is little loose and I don't know if it normal or is something wrong with my watch. Please any help is appreciated. Here is a picture of my watch. Thanks in advance....  

Any help please?

Is it screw down like the crown? Do you just need to turn it to tighten?

The watch manual says it is automatic, then it can't be turned. Thanks anyway.

had a problem with mine too and had to send it back to zurich for repairs, take it to BP ad.
