The Poljot 31679 movement
is a modification of the Poljot 3133 movement and features a Russian heart, powered by Swiss precision. In the early 1970s, Poljot wanted to modernize the 3017 chronograph movement produced until then. The number of pieces was to increase. The filigree wheel mechanism of the 3017 was to be replaced by a modern cam mechanism. The 3017 was already built on a production line imported from Switzerland by the Venus company (Fabrique d'Ebauches Vénus S.A.), based on the Venus 150. This proven approach was now to be used again in the early 1970s for the new chronograph (31 mm). A production line from Valjoux SA (today ETA, Swatch Group) was taken over and the movement was given an even more powerful Russian heart (balance). The basis for the Russian Poljot 3133 was the Valjoux 7734 or 7733, and the machines, plans and know-how were once again purchased from a very good source.
