This model breaks through numerous version bugs, allowing dedicated fans to own a high-quality replica that is accurate in size, movement, and details.Complete review: [link].Reasons to purchase:.1. Size: Close to official dimensions of 50 x 43 x 16 mm; JB factory dimensions are 49.8 x 44.3 x 16.4 mm.2. Authentic Bearings: The ruby in the skull's mouth serves as the actual bearing for the tourbillon, not just for decoration. The gem corresponds to the tourbillon's central axis, seemingly swallowing an energy ball, embodying the sci-fi essence intended by the original.3. Attention to Detail: The inner wall of the caseback is stamped with the RM052 logo, just like the original. The size and depth of the right eye gear closely match the original, with the central gem appearing bright and translucent. It features a matte buckle and a rubber strap made from imported Thai materials.4. Movement Alignment: Thanks to the consistent size and position of the tourbillon, the operation of the co-axial tourbillon can be clearly observed from the back, beneath the skull. From the front, the black oscillating weight is perfectly concealed by the skull's jaw, leaving only the escapement wheel visible below.5. Internal and External Quality: The movement is a custom true tourbillon movement from the Shanghai Movement Factory, with each watch undergoing high-intensity QE timing simulations. Additionally, waterproofing has been reinforced. JB Factory is dedicated to quality.This is another masterpiece following the double tourbillon RM001, Roger Dubuis RM053, and the Rolex tourbillon, showcasing classic fusion. Every JB Factory tourbillon comes with a genuine leather protective pouch. SJ meticulously crafts a super-realistic photographic representation of the Swiss true tourbillon mechanical movement for men.
