Beneath the intricate world map depicted on the dial, surrounded by the cities representing the world's major time zones for easily reading the time anywhere in the world, the Jaeger-LeCoultre Geophysic® Universal Time houses the new Calibre 772 self-winding movement which is equipped with the brand's Gyrolab® felly balance.

This invention dates back to a laboratory version from 2007 but is now available for the first time in one of the brand's mainstream collections. Furthermore, the movement offers a "true seconds", also known as "dead-beat seconds", which converts the 28,800 oscillations of the balance every hour into just 3600 jumps of the seconds hand, meaning that it advances just once per second - hence the "true seconds" name.
