Don't sell the 3717!
I today have mine for 3 weeks and won't ever sell it. I think it's the perfect combination with the 5001.
One is a sports watch and a classic Pilot's style, the other one is elegant and leisure. I love them both and will keep them both until my son will get them one day.
That said I must admit that I sold 3 IWCs (Mark XV, UTC classic and Portuguese chrono) and a non IWC (Union Glashuette) for my 5001. Unfortunately the 5001 costs a bit more than some other watches. And I really can understand you that you want it because I wanted it the same way as you do now. And I still am very happy with my decision. But I wouldn't have sold a 3717 for the 5001. In fact the 3717 was not avaiable then. It was just around last year's SIHH fair when I bought the 5001.
If you wouldn't like the 3717 very much that would be different. But maybe you'll regret it that you have let it go if you do. Maybe you'll miss it soon. You write "I own a IWC 3717 (love it) " and "I bought my 3717 two months ago and I have visisted the forum every day since." I guess that means something.
Maybe you can sell the Rolex and something else (?) and then try to save some more money for the 5001. Just a suggestion.
Just my 5 cents, good luck with your decision.
