This 1990 42mm. Russian Vostok Amphibian Submarine dive watch is UNUSED (NOS) and the manual winding movement was just cleaned by our watchmaker and is accurate. The vibrant green dial is uncommon and really ‘pops’ on the wrist. The original paperwork and box come with the watch. This stainleess steel back with chrome bezel is pristine. The crown is screw-down. The turning bezel is pristine. What an attractive piece of history to wear on your wrist.
