Jaeger-LeCoultre choose its caliber 898/1 for the current Geophysic 1958 replica watches, which they consider to be their most precise and reliable in-house automatic movement of this moment. This caliber has a hacking feature for accurate time-setting, a frequency of 28,800 vibrations per hour for high precision, a balance with fine adjustment by screws set into the rim and kifparechoc for shock-resistance. The automatic winding system uses ceramic ball bearings that requires no lubrication, and of course the tribute sports a soft-iron inner case that protects the mechanism from magnetism.
The Jaeger-LeCoultre Geophysic 1958 tribute replica watches have slightly grown (in comparison to the original watch of 35 mm) to 38.5 mm, meeting todays requirements, however pretty much kept its original shape. Although we are of the opinion that the form and dimensions of the original were slightly more balanced. Probably the original acrylic crystal in comparison to the slightly domed sapphire crystal of the re-edition is due to that as well.
Now, 56 years after the International Geophysical Year, Jaeger-LeCoultre replica watches decided to introduce a tribute to the original Geophysic, the Geophysic 1958. To us the new Geophysic are interesting replica watches, not belonging to any of the known Jaeger-LeCoultre model lines. It’s probably as well the reason that this watch is presented outside of the common spotlights of the SIHH, the place where normally new models are being presented.
