This is the new Master Compressor Extreme LAB concept watch. The most innovative feature is that the watch operates without any form of lubricant. The Jaeger-LeCoultre 988C is not only lubricant-free it is also resistant to extreme temps - 40° / + 60° C. This completely redesigned movement has gone through two years of development to achieve a high-tech movement that requires no oil. It is actually capable of running smoothly for years without any wear on the parts or deterioration of its performance. This concept watch and movement actually has six patents pending and it looks great too.
