@N2K: If you are looking for EDC collector watch that will hold a value for a long time, definitely I would suggest Daytona. It is a watch that every watch collector must have in their collection along with Omega Moon Watch just to name the 2 big brands. For investment, I would suggest Panerai but you have to do homework in which one to increase value in the future based on supply and demand. I have never lost money on Panerai and in fact I made a lot of money investing in it. For example, I made $3,500 on the Fiddy (paid $15,000 in 2005 sold for $18,500 in a heart beat in 2008). I made $2,000 on my Pam 190 (paid for $7,200 in 2007 and sold for $9,200 in 2011) now if you look at the prices of them right now, Fiddy is $25,000 here:
Those are just 2 examples to name a few that I made money on. If you want to invest in Rolex, it must be Vintage Rolex like the 50s and 60s Sea Dweller and Sub but you gotta know what you are doing otherwise you will get a swapped-out parts Vintage Rolexes (not original)that you never know.
