Yeah, Gen xtal wont fitnthe bpsd case BUT the good news is that the stock xtal looks exactly and I mean exactly like the f seriel gen. So unless you want a very specific look and are willing to let someone machine your case its just not really necessary..in my opinion the first thing that must be done is to get a gen crown on there, the stock crown is really bad. Then go TC on dial, hands, bracelet and dwo..The TC dial is a little crisper imo
