Well I must say I love both the watches. I've had my 5960P for a while now and love it. I just received my 5070P this week so I am one of the lucky ones I guess. I didn't expect it so quick but its here. So the answer to your question, I would choose the 5070P hands down for long term collect-ability. Its a sure bet. The movement will be no more after this year. Good luck
