Crown does not "click" easily

[ShiroTenshi]

My PAM111 is all perfect less one problem, after setting the time, the crown does not "click" back easily. Im not able to click it back in place by using my fingertip, instead I have to rely on the the crown guard lever to push it back.
Recently, its getting harder to push it back even with the CG lever, there seems to be some sort of resistance that is preventing it.
Any one has any idea?

Update: I removed the CG and try to press it in, sometimes it click, sometimes it doesnt, something seems to be preventing it from clicking easily.

Update2: I figured out a technique to push it back, I have to apply pressure starting from the bottom of the crown, and towards the centre to click it back. Someone tell me what is happening! lol.

1) the crown screw fastening the crown to the movement is not tight enough.

2) crown stem is too long.

Either one of these issues.

Is it a Noob?
Then most likely the hex tube nut have unscrewed it self from the case a bit.
Remove the crown and try tighten the hex nut.

Edit:
Try to tighten this one:

2) crown stem is too long.

Either one of these issues.

First one was it for when this happened to me.

Exact same issue with one of mine today. Crown had unscrewed from stem.

Any idea on how to keep it tight?

I had the same issue on my Noob 111M:

On mine the spring mechanism inside the crown was to weak.

So I exchanged the spring with a spring from a sub crown.

The spring from a sub crown is to long, so you have to crop it.
