Difficult Decision... To trade in or not?

[LocoNBroko]

Well, Im left with quite a difficult decision. Last week I made an attempt to buy an Omega 2531.80 and found the seller was trying to pass off a fake.
So yesterday I went to a dealer to take a look at buying a brand new one.
Of course I was wearing my 16610 at the time.

The dealer was very accommodating and not only had a new watch, but had a pre-owned one with all boxes and papers for a considerable savings over new.
They also had a pre-owned 2210.51.00 Planet Ocean Chronograph that was very interesting.

As we talked, the saleswoman asked if I would be interested in trading the 16610 in toward either of the watches and I explained that was not likely unless I was given a rather substantial cash settlement. She left for a few moments and came back to tell me she would offer both the 2531.8 and the 2210.51.00 and $500 for the 16610 if I would bring in the box and papers.

I have had no less than one and as many as 6 Rolex watches since I was 18 years old. I am currently down to 2 and was not in the market to get rid of either of them. BUT, I have also owned several Omega's over the years and they have always been excellent watches. In fact, it has always been my opinion that Omega did as good a job at building watches as Rolex, with the exception of the fact they are all eta based movements.

So, I have until 6pm today to decide... Opinions are welcome, and appreciated.
