Digital crown on apple watch s6

I'm worried about digital crown on my apple watch series 6.

It works great, it spins great too, but one thing worries me.It loosened a little and if you point it up and down with two fingers, you feel that it is not completely fixed. I have been using them since February and noticed this about 2 weeks ago, but did not betray the value, since everything works.

Should I worry, because I don't notice it with daily use. Just a question, could he loosen up and just need to be fixed somehow?
