purchased from the original owner a diver, this 16800 is in fantastic condition. The watch is well worn but also in amazing shape with the sides slightly matted to avoid reflection in the water while diving. The dial is perfect with great patina and the hands match nicely. The case has various scratches on it but remains thick, even and unpolished. The insert has faded to a grey color. The movement is running and keeping excellent time however the last service is unknown .
