Antarktida
Description
One of the watches made for Soviet polar explorers in the 1950s, this model was issued to participants of the first Soviet Arctic expeditions. The watch features a distinctive 24-hour movement, with the hour hand completing one full revolution over the course of a full day. This was critically important in the conditions of polar day and polar night, when a conventional 12-hour watch made it difficult to determine the actual time of day. According to available information, only 500 examples of this configuration were produced.
