Editor's Notes

Jaeger-LeCoultre's 'Geophysic' watch is modeled after a legendary chronometer introduced in 1958 as part of the International Geophysical Year, which is celebrated for advancements in science and exploration. Designed with a platinum case, it's powered by a calibre 948 automatic tourbillon movement and equipped with Gyrolab to reduce air friction and ensure precision. The beautifully detailed map decorating the face features the North Pole - an homage to the USS Nautilus expedition. It has a supple leather strap and single crown to easily adjust the world time disks when travelling.

We offer an eight-year warranty for all working parts and manufacturing faults for Jaeger-LeCoultre watches. For more information, contact one of our experts by emailing watches@mrporter.com
