A concept watch for some of the types of features and functionalities that might gradually find their way onto the world’s wrists in the same way that some of the technology from Formula 1 cars gradually trickles down to our everyday commute. This was not so much a production watch − in fact it was not at all a production watch − but rather a showcase for the very latest technology. In 2007, Jaeger-LeCoultre introduced the Master Compressor Extreme Lab 1. And in a mechanical wristwatch, it is the isochronism (regularity) of the balance that sets the ultimate limit to just how precise the movement can be. The Gyrolab balance, which premiers in the Jaeger-LeCoultre Geophysic’s Caliber 770/772 Master Compressor Extreme Lab 1 + 8 years = Gyrolab balanceĪs stylish, high precision timing instruments, Geophysic models have to be accurate. Two particular features of note in Caliber 770/772 are what Jaeger-LeCoultre calls true beat seconds, which are normally referred to as “dead” or “dead beat” seconds (because the hand is “dead” between the jump from one second to the next), and the unusual balance “wheel.” And as it would be showcasing new technology through a display back − and this being Jaeger-LeCoultre − it also had to look good.

The movement was developed from scratch to optimize the following features: precision, reliability, efficiency, a slim case, and automatic winding. The movement at the base of the new Geophysic collection is called Caliber 770 in True Seconds and Caliber 772 in the Universal Time. However, this being Jaeger-LeCoultre, you may not be surprised that both have a lot more under the hood than first impressions might indicate. The new Geophysic collection launches with two models, each available in stainless steel or pink gold: the True Second model displays time and date, while the Universal Time watch is a worldtimer.
