In my view the first thing on your list should be to get that Tudor back. I've seen them before with that notched bezel and generally not liked them but that one looks very nice indeed.
In terms of a Polerouter I would keep your powder very dry and bide your time - in my view somewhere in the order of a year. You need to enroll on the Universal Geneve forum and your first course of action should be to go through the first sticky: Universal Geneve Watches on Ebay. Once you've done that I'd suggest that you post up, over a few weeks or months, the occasional sample of a watch you are thinking of buying to see whether you have calibrated your eye properly. You will make mistakes but better to do it in the sandpit first; there are so many frankens and re-dials of this model range and spending more is no guarantee of success. Unfortunately the recent rise in values of these, thanks to the wretched Hodinkee amongst others, increases the incentive for the unscrupulous.
