History
In 1936, a Walkie-Talkie Wristwatch was made in Poland by an unknown engineer. During World War II, Poland was occupied by Nazi Germany and the Soviet Union. Shortly after the occupation, the agents of HYDRA, the Nazi deep science division, built a factory in Poland near the coast of the Baltic Sea. That factory was later destroyed by Captain America and his team of soldiers, the Howling Commandos.
