Forget the case from Natalie, it doesn't even has lugholes and the shape of the lugs isn't correct either, it looks more like a 16220 case (lugs wrong). You could shape it if you spend a lot of time or money on a modder to do it, but for the price...
You'd better spend the money on a gen 16000 case, which is closer to a 1016.
For the dial: if you really want a Space Dweller, take the ingod dial. Very good printing however it isn't 100% correct. Finding a good Explorer dial can be very difficult, Nathalies are to expensive (sometimes you can find a gen dial for that money), the ebay ones from mahand1 are not too bad, yukis are wrong and MBW dials have not the T<25 text.
If you want a normal Explorer or Space Dweller, well ... you decide.
