Problem with my pam 250

[Matrim604]

The ring around the strap bar release button came off while I was changing straps (visible on the right push button). The button itself still works, but kinda wobbles around in the now too large hole. I tried just popping it back in but it won't stay, and it doesn't look like it can be screwed or snapped in. Has anyone else seen this or had a problem with this? Just got the watch about a month ago, think warranty will cover it? Here is a picture, I still have the piece too, though I didn't include it in the picture.
