    After a long process of cooperative research and development, the high-end watch industry has finally made breakthrough progress in recent years. In 2008, Jaeger-LeCoultre launched the world’s first watch that does not require lubricant in the movement-the Master Compressor Extreme LAB concept tourbillon watch, which dropped a bombshell in the industry and also led a ‘ The Zero Lubricant Revolution. ‘ In 2009, Jaeger-LeCoultre launched two revolutionary works, namely the perpetual calendar tourbillon watch of the Master Grande Tradition and the standard pointer minute repeater watch. They are equipped with Jaeger-LeCoultre silicon escapements, marking a further step towards the goal of zero lubricants.
    The perpetual calendar tourbillon watch and the standard pointer minute repeater watch are made of precious metal. The case, bezel and lugs are finely polished, and the dial is decorated with Paris studs. Although the elegant Prince-in-law hands and hand-carved time scales are not unique to Jaeger-LeCoultre, the beauty in them is undoubtedly the product of reaching a certain artistic height. These two masterpieces from the Master series have also passed the new and more stringent ‘Jacques 1000 Hour Observatory Test’, which not only tests the overall performance of the watch, but also verifies the accuracy of the new silicon escapement.
