go for it my friend, i did a similar thing with my rolexes, i sold all my collection which included 2 x SS Daytonas...to buy a 5980/1A and a 5712/1A. i have never looked back since. Personally i did not buy them for financial gain or rarity etc... i bought them purely to step up from Rolex of which i was an avid fan for 11 years and start a new era of collecting Patek Philippe watches instead...albeit a bloody expensive decision!!lol!

I just traded 2 SS Daytonas plus cash for a 5980. I loved Rolexs, but got bored with the Daytonas. I keep a non-date Submariner to use as a "rough use" watch.
