What is the worth of this Omega Seamaster?

[kingblackbolt]

Can I get everyone's opinion on what this OMEGA SEAMASTER PROFRESSIONAL CHRONOGRAPH w/ TITANIUM BAND & GOLD BEZEL should be selling for? I have the seller down to a decent price but I'm not sure whether this is really a good deal or not? Is it harder to resell a Gold Seamaster as opposed to a SS version?

Comes with box and papers although the boxes are not in good shape, watch looks to be in good shape too but the back of the case is scratched (see pics) and has the word "Titane" on it so if I wanted to replace it it would be hard right?
