"New" Sea-dweller???

[Letsgodiving]

Hey folks, I'm new to this forum and as of last weekend a new Sea-Dweller owner. There are a lot of knowledgable people here and I have a question for you.

I bought a "new" SD from my local AD but it is an F series. I didn't realize this until I got it home and started looking at the paperwork. I called them and s/w the manager about my disappointment that I hadn't received the new Z series and explained my concern that I may have watch that is possibly 4 years old as an F series watch.

He told me that it is a myth that the first letter in the serial# denotes the year of manufacture. He was aware of the various lists on the internet but said they were false. I wasn't buying it and he said he could order another if I really wasn't happy with this one but he could not guarantee it would be a Z. He also encouraged me to call Rolex directly to confirm what he was saying.

I called Rolex and they weren't very helpful b/c of their policy of not revealing anything about a serial # of a watch w/out having the watch in their possession. But thier rep did confirm that the fact that my serail # has an F in the front of it has nothing to do with the year it was made. She also stated these lists are false.

I see these lists all over and all the "new" Rolex watches on Ebay etc. are the Z series. Who is correct here? Did I get stuck with a watch which is potentially already 4 years? Which, by the way, I paid the 2007 retail price for. Any feedback would be much appreciated!
