It looks like I'll have to shell out (no pun intended) for a Cosmograph. Could have saved myself a lot of time if I'd done that in the first place!
If you want the new one you'll have to wait years unlesss your sleeping with a dealer or are willing to pay over £4k above RRP from someone like Watchfinder and if your prepared to do that you might as well get yourself on a Patek buy list for a Nautilus.
