|1957 – 1958 was designated International
This was an international scientifi c
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 fi rst
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 fi elds 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 fi tted with an
automatic movement and renamed
