From what I can see, the TC case could present some problems when installing a gen crystal retaining ring. There is a tiny ledge around the rehaut and a gen retaining ring will be slightly raised once it's pressed on. Have any of you milled this away? and if so, did you leave a tiny portion at the base of the rehaut sidewall so that the gasket height will not be affected?
I guess the ledge is there so that the TC bezel has a bit of clearance so it doesnt rub against the case. Which probably means that once the ledge is milled away, one will not be able to use a TC bezel assembly again.
