Is this a problem with my 176?

I have just purchased a used 176J in mint condition from a very reliable dealer.
I notice there is a very very slight lifting between the "bezel" or upper part of the face and the body of the watch that the face of the watch sits on, at the 10 o clock position.
Its just not flush titanium on titanium at this point.
(I hope I am describing this adequately)
Its like a tiny slit that a fine piece of paper can fit into but only for a mm or 2 deep. (Its really tiny to be honest, my wife could not see what I was even looking at, and thinks I am nuts, firslty for buying an expensive watch that I need to wind everday and now this!!!)
I'm not sure if this is a problen.
Any input would be appreciated.
I'm really loving the look and the feel of the watch, its fantastic...
