Poljot P3133

The Poljot P3133 is a manual-winding chronograph movement developed from the Valjoux 7734. It beats at 21,600 vph with 23 jewels and provides 42 hours of power reserve, reduced to 37 hours when the chronograph runs. The movement includes quickset date and Anti-Shock protection. Produced by the First Moscow Watch Factory from the 1970s using Valjoux machinery acquired by the USSR, it powered Russian chronographs including the Moscow Classic and Strela before being discontinued.
