The Geophysic Chronometer is amongst the most important watches in the history of Jaeger-LeCoultre, representing the manufacturer's values of precision, robustness and aesthetic purity. Made at a time of fundamental scientific and political developments, it was directly involved in this historical context.
To match the model that would resist any type of challenge, in particular water-resistance, anti-magnetism, adjustment, etc., the name Geophysic Chronometer was suggested, also as it perfectly met the criteria and values of the International Geophysical Year (IGY). This particularly significant scientific event was organized on the initiative of the United States and took place at the high point of solar activity, from 1 July 1957 to 31 December 1958. It was also the first year of the Space Age, with the launch of the first artificial satellite, Sputnik 1, on 4 October 1957.
The models were fitted with Jaeger-LeCoultre's first chronometer movement, the calibre P478/BWSBR developed in 1957, new water-resistant cases with soft iron domes to protect the movement from magnetic field influence up to 600 gauss, thus meeting the needs of research scientists working on polar bases, in laboratories or inside submarines. The origin of this watchmaking project was the call for "resistance to any type of challenge". Consequently, the cases were able to withstand magnetic fields, given that magnetism was also one of the scientists' main areas of study. Precision, guaranteed in mechanical watchmaking by the term 'chronometer', is another crucial necessity as every science requires exact measurements.
The precision, robustness and reliability of the Geophysic Chronometer made it a symbol of excellence and the logical choice when Jaeger-LeCoultre decided to revive the Geophysic tradition in 2009.
