Is JB Factory Richard Mille RM52-01 real tourbillon - blue worth buying?

Richard Mille Wristwatch RM52-01 model is produced by JB Factory with carbon fiber and Carbotech case, standard case diameter and high-precision automatic Super Clone mechanism architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.
1. Dimensions are close to each other
The length-width-thickness of the original is 50X43X16 mm, the length-width-thickness of JB Factory is 49.8X44.3X16.4 mm;
2. Real bed
The ruby in the skull's mouth is not an ornament, but the real seat of the tourbillon. The stone corresponds to the tourbillon central shaft surrounded by the upper and lower jaws; It looks as if a ball of energy has been swallowed, and the science fiction atmosphere that the original wanted to convey is thus revealed;
3. Details are in place
There is a steel stamp RM052 on the left inner wall of the case's inner cover, just like the original. The size and depth of the gear in the right eye are very close to the original, the stone in the center of the forehead is red and sparkling. Additionally, a matte embroidered buckle and an imported Thai rubber strap are used;
4. Mechanism alignment
Since the position and size of the tourbillon are the same as the original, when viewed from the back, the operation of the tourbillon rotating on the same axis as the stone, under the neck of the skull, can be clearly seen. When viewed from the front, the black balance is completely hidden by the lower jaw of the skull; only the exit wheel running under the skull is visible;
5. Careful inside and out
The movement is a real tourbillon mechanism specially made by the Shanghai movement factory. Each hour is QE time-tested in a high-intensity simulator; Additionally, its waterproofing has been strengthened.
JB Factory — devotes as much love to its work as it does to its mechanism! This is another important work following the double tourbillon, RM001, Roger Dubuis Excalibur, RM053, Rolex tourbillon and Classic Fusion! Each JBFactory tourbillon comes with a genuine leather protective case as a gift.
