Why is APS Factory Jaeger LeCoultre Master Tourbillon Q13234E1 Super Clone Watch so expensive

Custom real tourbillon costs a lot: The main cost of the APS Factory Jaeger LeCoultre Master Tourbillon Q13234E1 Super Clone Watch is the custom real tourbillon movement. It solves coaxial running and slim structure. The tech R&D and parts cost are expensive.
Hard polishing lowers the good rate: Case curve and dial details are 1:1 to the original. Hands and bridges need fine hand chamfer. The high scrap rate directly pushes up production cost.
Fine time adjustment and low capacity: This kind of top Jaeger-LeCoultre tourbillon replica watch needs multi-dimension dynamic timing and waterproof test before it leaves the factory. The time-consuming QC process and limited capacity together push the price up.
