After a whole lot of thinking and with good help from you guys at the Roolex forums, I bought the Rolex Sub from Bobs watches that is shjown in this thread.

The Watch is in excellent condition but I have some thoughts about the case. I hope you guys can help me with this!
First of all a quick talk about Bobswatches. First I emailed them and ask them if the watch was still available.
No problem, they said. The watch is in a perfect condition and it would look stunning on you!
I sent them a couple of email and asked them if the watch was serviced and if they know anything about the previous owners.
I also asked them if they could do a couple of bucks with the price.

I must say that they were really nice but they did not answer any of my questions. I didn't got the best impression. I was sending a couple of email but I don't think I talk to the same person twice.

Anyway! I ordered the watch in spite the concerns I got from the corresponding.
I really like it and it was in fact a watch from 1970, the year I was born!

A couple of weeks later I found the box from Bobs watches in my mailbox.
In Sweden we usually get a note from the post office and we need to go down to the local post office to show a ID to get the more expensive packages.
In this case the xxxx$ box was in the my mail for anyone to lay there hands on!!
I don't know who to blame, Bobswatches or FedEx perhaps? Luckily it went ok and I got the watch!
Now to my question! Do you guys think this watch is in a "too good condition" not to have been welding on? (sorry for my broken english)
In the Swedish forums one or two think it has been renovated and welded by ABC Watchwerks.
What do you think? I really don't care, and it is not really that important if it has some welding done to it, I just want to know.

A couple of pictures below for you to look at.
