Fair Market Value for this vintage Seamaster DeVille?

[powerfade]

I was browsing the auctions and came across what I think is a beautiful vintage Seamaster. I'm wondering if the Omega experts here can suggest a FMV on this watch. Of course I pay 15% Buyer's Premium + dreaded 13% sales tax on this. I'm going to do my homework now and see if I can get any price discovery on this watch through past sales.

There should be 4 rows of 5 watches at this page. It's the bottom row, 2nd from left. Let me know if this link isn't working for some reason.
