I think that from all the watches that you have mentioned, the AP's are the best choice. I think that the 15305ST #1 (the open skeleton) is the safest bet when it comes to re sale. I think that the other "novelty" ROO while fun, does not have the charm of the original 42mm offshore (personal opinion). As far as the hublot's are concerned I think that there is a new model by Jay Z that will hold its value well if not increase as it is limited, might be hard to find.... check it out though.
