This replica watch was made by JB factory several years ago, it is the first replica Rolex with tourbillon movement I have ever seen. The watch is made with 316L stainless steel and has a thick black PVD coating on the case and bracelet. The tourbillon device, which you can see through the window opened at 6 o’clock, is real. JB factory has been making high quality tourbillon replica watches for many years.
