There is a fix for the loose bezel over at either Rep Geek or RWI. It involves dental floss! No joke. I have been planning to fix the loose bezel on my SA BlackSteel, but just haven't gotten around to it.
EDIT: I found the post on Rep Geek...

My Milgauss movement had issues right after I started wearing it. I sent it back to the dealer, and since I got it back (serviced) it has kept time a bit better than my genuine Swiss ETA LV Submariner. Best $100 I've spent in a long time!
I have the same watch...bought it from Stan. Question, have you taken the caseback off? I removed mine and noticed that the anti-magnetic cover isn't there. I'm thinking they only install them on the ETA version.
I love this watch! I bought a 21J version from Stan. It doesn't have the anti-magnetic cover in it, but also doesn't have the etched crown. I just got a high-beat movement in to swap into the watch. I wish the rep lume glowed different colors like the gen!
Oh, it doesn't need to be functional. If I'm ever deep enough in the ocean to need a helium escape valve, I am wearing cement shoes! I just like to play with all of the cool things on the watch like divers extensions and helium valves.
