The Jaeger-LeCoultre Master Compressor Extreme LAB 2 was introduced at SIHH 2010, in January. The Extreme LAB doesn't have any complications, like a tourbillon or perpetual calendar. It will, however, have some very high-tech Seiko SNA629P1 functions, even if they aren't considered complicated by traditional definitions. The difference between the 781 and 780, would be that the 781 Calibre movement features a professional silicon escapement.
For instance, it has a patented jumping digital minutes counter, a push-button crown function selector, an advanced anti-magnetic silicon escapement, a black zirconium-ceramic bezel, a rotor that is installed on lubrication free ceramic ball bearings as well as an advanced multi-adjusting strap. Even the case is high-tech. It is a dual-ring-case: Seiko SNA629P1 Watch sandwich structured case with carrier-chassis and movement container. It's 143 components and is made of an advanced titanium alloy, exclusive to Jaeger-LeCoultre, called TiVan15. Powering the Master Compressor Extreme LAB 2 TiVan 15, is the Calibre 781 (Calibre 780 is in rose gold version).
The benefits of this kind of high-tech escapement is that it is anti-magnetic, runs with lower friction, doesn't need periodic oil lubrication and it is lighter (which can allow higher speed and accuracy). The power-reserve is 60 hoursThe dial, which is skeletonized, offers a great view from the movement. The patented mechanical digital Sector 04940 Men's Watch jumping seconds is displayed at 12 o'clock. Using two discs,
