The sweep hand of the watch gives a reading of the radioactivity, 12 o'clock representing no appreciable radioactivity, 3 o'clock representing the point at which a man would become ill, 6 o'clock indicating the point at which an hour's exposure would result in an 80 percent chance of death and illness would strike almost immediately, and 9 o'clock indicating 15 minutes exposure would result in certain death within 24 hours. Readings above this level simply indicate less time until death. The sweep hand would lock at 11 o'clock should radioactivity ever get that high, which is extraordinarily unlikely. Nuclear materials will have radioactivity which range from 1 o'clock to 7 o'clock, depending on how they are stored. The watch is waterproof
