Great find and great thread. Have always liked the Poljot chronos but very interesting to learn more about the other makers listed here. Just picked up one of the Gagarin reissues.
Early 1980s grey dial Poljot "Flight" 3133 chronographs, models used by at least 25 cosmonauts during a dozen spaceflight missions... among whom first female to make a spacewalk; Svetlana Savitskaya (July 1984)
Amazing Russian made toolwatches, never hyped nor marketed and which can still be bought for the cost of a new Omega NATO strap 👍
