Arrgh, this is an evil question!
I can narrow it down as follows:
Vintage=1665 Double Red Sea-Dweller (or maybe a 6542 GMT, or maybe a 1675 GMT). But okay, I'll settle on a 1665.
Modern=Rainbow Daytona (specifically rose gold with black dial and gold flake subdials, either 116595RBOW or 126595RBOW).
Now, if I had to pick between the DRSD and RBOW -- this is an insurmountable task.
