What are the advantages of Jaeger-LeCoultre's self-produced movement?

Jaeger-LeCoultre belongs to the category of super watches, and all departments use self-produced movements. In this class of super watches, each brand has its own movement, and its polishing and workmanship are different. The most technical content of a brand is the top model, and Jaeger-LeCoultre's advantage lies in its huge and complicated models. In a huge and complicated scope, Jaeger-LeCoultre is best at integrating tourbillon, San Wen and the perpetual calendar. Jaeger-LeCoultre is a top brand that can be played with tourbillon. His celestial body, tourbillon, is beautiful, complicated in workmanship, and surprisingly expensive. Tourbillon, minute question and perpetual calendar are the three complex functions of watches, and few of them can be combined together in the world, which shows that Jaeger-LeCoultre has superb skills. If we have to say the advantage of Jaeger-LeCoultre's self-produced core, I think it is the ability to innovate. Jaeger-LeCoultre is very innovative and has many patents.
