Complete review: https://v.qq.com/txp/iframe/player.html?vid=x3201jizbjm Reasons to purchase:1. Close dimensions: Official size: 50*43*16mm; JB factory size: 49.8*44.3*16.4mm;2. Real bearings: The ruby in the skull's mouth serves as the real bearing for the tourbillon and is not merely decorative, corresponding to the upper and lower jaws that enclose the tourbillon's central axis, as if swallowing an energy ball, thus embodying the sci-fi concept that the original intended to express;3. Precise details: The inner wall of the watch case on the left side is stamped with RM052 just like the original, and the size and depth of the gears on the right eye are close to the original. The central gemstone on the forehead is pale red and transparent, with a matte buckle and imported Thai rubber strap;4. Accurate movement alignment: Thanks to the position and size of the tourbillon being consistent with the original, from the back view under the skull’s occiput, one can clearly see the operation of the tourbillon coaxial with the gemstone. From the front, the black balance wheel is just obscured by the skull's jaw, leaving the escapement wheel wandering beneath the skull;5. Both internal and external excellence: The movement is a customized true tourbillon from the Shanghai movement factory, and each watch has undergone high-intensity simulator QE timing tests, along with enhanced waterproofing.JB Factory - focused on the core and putting in genuine effort! This is yet another masterpiece following the double tourbillon, RM001, Roger Dubuis King's series, RM053, Rolex tourbillon, and classic fusion!
