MIR (peace in English) watches where produced by the chistopol (Tschistopolsky) watch factory probably in the 1960ies.
This watch has a cool dial with the word antishock inscribed bellow the jewel count indication on the dial. It mounts an 18 jewels movement with date complication but I did not open it so I am not sure of which caliber is it.
Original name in Cyrillic: МИР
