cj, I guess it is a mater of luck, my bezel is very tight. Anyway, regarding your question, I found in the forum two methods to fix a loose bezel, not in this specific model but mostly of the bezel are look a like.
First method, disassembling the bezel, you could find this method used to align the bezel on an Omega SMP. You need to remove the whole bezel, using a very sharp knife and using the right amount of pressure. Internally, there is an open hexagonal spring wire, you before re assemble the bezel slight open the spring.
Second method, without dsassembling the bezel, cut a small rubber band, pull it to get it thinner and carefully insert it under the bezel, the more rubber band you could insert the tighter the bezel will fell.
Be aware that I could not warrant the results with none of the method described above. If you decide to perform any of them, do it under your own risk. The first one require more skill, it's the one I tried on my SMP, and the second is more in the MacGiver side. Also I suggest you to do a like more research in the forum, the method I just describe are not mine, I found them somewhere here in the forum.
