not exactly , I repeat : I already have eta7750/sterile dial/hands .but the case that I have is not really suitable: not very far, I think .... but I have to adjust dial /crown tube thickness - removing -1mm of steel if I can find a rep case ( close to gen's shape ) the 7750 will go directly in place regarding thickness but I need to know if my sterile dial's diameter ( visual index) have the good diameter to the case's opening and vice versa it was my first small request at the beginning - I didn't imagine that it will occur so many questions thanks you for your interest ps : I think that the gen 3717 case is finest - rep case too I hope
