My ROO crown came off

[ykbaek]

Hello

I am in Toronto, Canada
And my crown from ROO came off few days ago.

I was turning it and suddenly the whlole crown with long stem came off and kind of worried. Will it be an expensive fix? Where should i take it?

Did bit of research but cant find right answer other than a guy in Ottawa for a fix.

Hope its not serious, any advice will be greatly appreciated.

Wondering if i can take it to a highend watch stores and get an easy fix.

Thanks
