hello all, I am interested in the following vintage seamaster: https://www.chrono24.com/omega/seamaster-de-ville-automatic-gold-vintage-14770--id14525633.htm it clearly has been polished, and I imagine the dial has been touched up, but I don’t know anything about the value of said watch after restoration, or if it is a desirable piece. Also, what year is this piece from? Thanks!
