I don't know the exact year it was made but it would be around the middle of WW2 when the V2 program began.
There are several of these ALS watches, but obviously extremely rare. The V2 program was top secret, the existance of these
watches was unknown until after WW2 when they were captured. The United States wanted the rocket technology so Von Braun
was not tried as a criminal and brought to the United States with other key scientists. And so began NASA.
