This watch was never sold to the public in the Soviet Union. It was only given to the members of the 16th expedition to the Antarctis.
On the dial you see Antarctica with 6 Soviet Antarctic bases marked with artificial rubies. The text below the continent is АНТАРКТИДА 16 САЭ Antarctic 16 SAE. The expedition lasted 1970-72 and the watch was intended for members and other people related to the expedition. The 16th expedition was much bigger than previous Soviet Antarctic efforts in total 566 people, including 354 as crews of ships.
How many Antarktidas were produced is not known. Presumably some hundreds. The model is very rare, because most of them are usually still in possession of families of the polar explorers.
