I bought a C60 Atoll in early May and the bezel felt, to me, quite loose, with a noticeable gap when turning or even touching it. It had a lot of lateral movement The first Customer Service rep I contacted said yep, that's an issue, and I returned it.
Later, CS said they would all be similar, and an exchange may not be any better.

I actually asked them to check a few out, and send me one that was less loose - or perhaps less "wobbly" - than my original one. It's coming next week.
I'm hopeful it's better. I get that there's a certain degree of tolerance, but I simply wasn't happy with the one I received. Looking on youtube you can see that some are looser while others are more solid.
So yes, it seems some people get ones that are more loose than others.
