This is an uncommon and exotically dialed vintage 41.5×45.6mm. Russian Vostok dive watch that appeared on the Apple T.V. series “For All Mankind”. This watch has a turning bezel and a screw-down winding crown. The manual winding movement was cleaned recently. The “banana” dial sure is interesting. No doubt, this watch was copied from the Omega Seamaster 200 “banana dial” (a name I coined). This watch is uncommon and super-cool with provenenace.
