Condition 96%. Beautiful Soviet era military Vostok Amphibian mechanical watch with rotating bezel and screw down crown. These are very nice quality watches, and on the rise in terms of collectibility. The Vostok Amphibian features an ingenious sprung-loaded crown/stem design that creates a single piece design when pulled out and a two-piece when screwed down. This was done to stop the stem damaging the movement under extreme pressure. The 'wobbly' nature of the crown when unscrewed is aprt of this and absolutely how it should be. This example is in fine condition with light signs of wear/use. It is keeping good time and is supplied on a new single pass nato strap. Case size is 39mm not including the crown.
