The new Jaeger LeCoultre Geophysic 1958 is available in three versions: a red gold version (limited edition of 300 pieces), a stainless steel version (LE of 800 pieces), and a platinum version (LE of 58 pieces available only in JLC boutiques). All have a diameter of 38.5mm. The Geophysic is considered one of the most important models in the history of JLC. It was originally produced in 1958 which was International Geophysical Year. Today the watch uses the calibre 898/1 while the original version used the calibre 478BWSbr. The new movement has has a number of improvements, although the original movement had the best features that could be found in a watch at the time including a stop seconds function, a shock absorber, and an soft-iron inner case to protect the movement from magnetic fields up to 600 gauss. The original watch was made in honor of the USS Nautilus, a submarine that travelled under the ice cap of the north pole to find out more about plate tectonics. After three days underwater, the submarine surfaced with all the information needed to complete the study. A new watch with some history behind design; what more could someone ask for?
