You could always try Ebay with a reserve and a "Buy It Now" price. If they don't sell you're only out a few bucks for the cost of the listing.

Holy cow, I bought a small ladies 1980's gold Omega watch, they're awesome (and fashionable here right now - 60s 70s or 80s only). I found mine in the pawn shop, where it was a total steal since i was basically paying the wiight of the watch on gold + a little extra for "Omega". I bet I'd love your watches. But I'm also a stingy bastard so you wouldn't score much selling to me. ;)
