The incarnation of the 1950's designs, the UFO or Disco Volante is a great indication of a watch manufacture era. This VC is just stunning in person despite its aging dial. The correctness of the piece is undeniable and comes with an unsigned crown and beveled crystal which enhances the hand engraved bezel.
