The Poljot 3133 (similar to 31679) movement
Has a Russian heart, driven by Swiss precision. In the early 1970s, Poljot wanted to modernize the 3017 chronograph movement that had been produced to date. The number should increase. The filigree ratchet mechanism of the 3017 was to be replaced with a modern cam switch mechanism. The 3017 was already built on a production line imported from Switzerland by Venus (Fabrique d'Ebauches Vénus SA) based on the Venus 150. This tried and tested procedure was to come into play again in the early 1970s with the new chronograph (31mm). This time a production line was taken over by Valjoux SA (now ETA, Swatch Group) and the movement was given an even stronger Russian heart (balance). The basis for the Russian Poljot 3133 was the Valjoux 7734 resp. 7733. The machines, plans and know-how were bought again in a very good place.
History MakTime
However, the 31mm chronograph production line was taken over by the Moscow company MakTime von Poljot from 2005 and thus saved for the time being. The good standard of production was maintained and in large parts even improved. MakTime then unfortunately had to stop production in 2012 due to bankruptcy. Too few quantities were sold internationally. In the meantime, the company had 700 employees divided into the production of the 31mm chronograph movement and the clocks in Moscow. The other employees worked at the Penza watch factory and produced smaller movements for ladies' watches under the Zaria brand.
History of Poljot
This goes back to the year 1930. At that time the factory was still called the "First Moscow Watch Factory". The first movements of the new Type-1 for mass production were manufactured for the first time on an imported production line of the Dueber-Hampden Watch Company, Ohio. By 1952, production had increased to 1.1 million watches. The country should be supplied with good watches. The military and science needed more precise clocks. In 1964 the name of the factory was changed to Poljot (flight). The watch industry was not only a necessity but also a showcase project in the Soviet Union and Poljot became the greatest success. Other works such as the alarm plant Poljot 2612 and many more were produced. In 1990 the production level was 5 million watches a year. Hundreds of employees made this achievement possible. In 2004 Poljot had to go bankrupt despite a long and proud history. Many highly qualified employees lost their jobs at that time.
