This piece is interesting because it is from the transition period were the soviet union disintegrated (about 1992), the dial is still marked as made in URSS but the caseback is inscribed as Made in Russia. This feature is not uncommon for watches of this period, see also watch #40.
It mounts a caliber 2414, manual wind with 17 jewels.
