There is one guy on WatchUSeek that says if this is a genuine Blancpain. However, this is not the modern Blancpain (in Le Brassus). Instead, this watch is from the old Blancpain (in Villeret - hence the "Rayville"). Now I really want to know how much "Rayville" Blancpains are worth compared to "Le Brassus" Blancpains. Any insight?
