This is an uncommon and exotically dialed vintage 41.5×45.6mm. Russian Vostok dive watch that was leased to the Apple T.V. series “For All Mankind” and worn by a Russian Astronaut on the show. This watch has a turning bezel and a screw-down winding crown. The manual winding movement was cleaned recently. I love the gradient green dial! This watch is uncommon and super-cool with provenance.
