Raduga / Радуга
After World War II, the Chistopol Watch Factory focused heavily on wristwatch production. This lead to a proliferation of discrete brands in the 1950s, all powered by Chistopol movements. These brands included Almaz, Chaika, Druzhba, Kama, Kolos, Mir, Pobeda, Raduga, Rubin, Saturn, Sputnik, Uran, Volna, Vostok, and Yantar.
The Raduga brand (Радуга, meaning "rainbow") was produced in the 1950s and early 1960s. Raduga watches manufactured for domestic sale were powered by a 17-jewel caliber 2603 movement. Export Radugas were found with caliber 2605 (17 jewels), caliber 2209 (18 jewels), and caliber 2809A (22 jewels) movements. The Raduga brand was retired around 1964, when the vast majority of brands from the Chistopol Watch Factory were consolidated under a single trademark: Vostok.
