Market price for a pre-owned Seamaster or Seamaster Chrono?

[Cobra]

Just curious on everyone's thoughts.

I like the classic blue face Seamaster and Seamaster chrono and am wondering what typical used ones in very good shape sell for? I stopped in at a store in Toronto, Canada that specilizes in pre-owned watches on the weekend and was surprised by some of their prices.

Also, on each used piece they had posted a "list price" (price when new) as well as "their price" which I thought was a bit misleading - after all, these weren't discounted "new" watches, these were all pre-owned.

There also wasn't always that much of a difference in price from "new". Given AD's probably work with a 40-50% margin on most brands I came away thinking I just looked at some VERY expensive "used" watches.
