Notes
1957-
Wostok, Watch Factory Tschistopol
chronometer
most nickel plated, some gold plated
Breguet hairspring
strange: indirectly driven minute and second as well as the escape-wheel bearing underneath the balance allow a big balance (design similar to the Zenith 135)
The movements for Wolna- and Wostok watches had to pass tests similar to those of the COSC. Movements which didn't pass the test, were used for the cheaper brand Almaz (cf. Wostok 2809B).
