Вот официальная справка:
Ostwok watches were manufactured by Vostok starting from approximately 1995 for the Swiss company Ostwok S.A. in Illnau. These watches differ from 'original' Vostok watches only by the use of the Ostwok logo on the dial. The company went into liquidation in 2000, and by 2002 it was ended.
