The Geophysic Story Do you know that Geophysic watches get their name from a model that's a part of history as well as the Jaeger-LeCoultre heritage? A legendary chronometer created in 1958 as part of the International Geophysical Year, rich in exploration and scientific discoveries. Concealing the complexity of the calibre of Haute Horlogerie under a simple appearance and functions, the pieces of this collection say a lot. Most of them are endowed with True Second, the result of a truly sophisticated assembly. With this device, the second hand shifts by making a jump each time, which is kind of unusual for a mechanical movement, and all of this is done without interrupting the watch's functioning. These watches are also equipped with Gyrolab, a unique balance wheel whose non-circular configuration reduces air friction. A firm advance when it comes to the precision of the watch.
