The Vostok Company was founded in 1942 when one of the Moscow watch-making plants of the First Moscow Watch Factory was evacuated to Chistopol, a small town located on the Kama River in Tatarstan. Only defence equipment was produced during the war years, but as soon as the war was over the company started making mechanical wrist watches. However, the Company did not begin using the "Vostok" brand name until the 1960s. Presumably "Vostok" brand was named after the Vostok space programme, which gave the initial advancement of the USSR in the Space race (as some others soviet watch brands, named to space topics in 1960s - Poljot and Raketa). The company was appointed an official supplier of watches for the Defence Department of the Soviet Union in 1965. This year also marks the creation of the well known Komandirskie ("Commander's") watch
