1957 –1958 was designated International Geophysical Year. This was an international scientific effort in which 67 countries took part in making observations and carrying out experiments in various aspects of the earth sciences such as seismology, electromagnetism, glaciology, radioactivity and solar activity. The Jaeger LeCoultre “Geophysic” wristwatch was inspired by the Geophysical Year. To publicise the effort, watches were given to the crew of the the US Nautilus, the first nuclear powered submarine, after its trip under the North Pole in 1958. This watch was made to be anti-magnetic to 600 Gauss to combat the effect of magnetic fields that could disturb the timekeeping qualities of the watch. 1038 pieces were made in stainless steel and 30 in gold. After 1962, the Geophysic was fitted with an automatic movement and renamed the “Geomatic”.
