A good example of the famous and collectible Vostok Amphibian winds, sets, runs as it should; unknown when last serviced.  All functions work fine, including the rotating bezel and the date calendar (non-quickset on this model).  Green dial has KGB insignia and polished silver hands and hour markers.  Polished stainless case and acrylic crystal in very good with minor scratches here and there; green dial with KGB emblem very good to excellent.  Black leather band.  200m water resistance not guaranteed.  Manufacture date unknown.
