very nicely preserved 16800 from 1986.   The dial and hands have dark pumpkin patina and the surface of the dial has turned totally matte.  The case is well proportioned and was possibly lightly polished in the past however original bevels are still visible.  The bezel is sharp and the insert has turned a ghost grey with a dark amber pearl.  The bracelet is original, fully linked and has a hardly any stretch for its age.  Movement keeping excellent time however last service is unknown.  Comes as watch only.
