How much do omega Seamaster 300m cost?

It depends if it is real or fake. It was made in 1848 so I would believe it would be around $100-$10,000 dollars but I doubt it would be cheap and there are not much left in the world and if someone could over it to you cheaper then $5,000 dollars that's pretty good because with understanding I have just seen a picture of this watch and it looks pretty dear but it depends if it is digested with gold but anyway your welcome!
