Repair of the Automatic Watch “Vostok 2416 b”watchadmin
Chistopol Watch Factory was founded in 1941 in Chistopol, Russia. The equipment arrived from the evacuated Moscow Second Watch Factory. In the spring of 1942 the factory started producing military equipment. The enterprise worked for the army and it was a secret place. In 1943 Chistopol Watch Factory began manufacturing peaceful production, the first product was “Kirovskie” watch for men. In the postwar years the factory began developing, manufacturing and producing new models of the watches “ZiM”, “Volga”, “Pobeda”, “Vostok”, “Mir”, “Volna”, “Saturn”, “Kosmos”, marine clock etc. Later the factory became the main supplier of the USSR Ministry of Defense, at that time the factory produced “Komandirskie” and “Amphibia” watches with water resistance up to 200 meters. Since 1970s the factory began to produce watches of 24hh caliber with a calendar and automatic winding. Today the plant is bankrupt and the watches are produced by subsidiaries.
