The blue-and-black bezel, the crown protector and the black embellishment of the rubber strap add striking details to this watch. The movement is suspended in the middle of the watch case. The base plate of the movement is connected to the watch case by four steel cables. The braided steel cables are only 0.35mm thick. Combining rigidity and toughness, this structure protects the movement. These cables are tightened by tensioning devices at 3 o’clock and 9 o’clock positions and pulleys acting as tower bridges at the four ends of the movement. Richard Mille RM50-27-01 NTPT Blue Forged Carbon Skeleton Dial Replica Watch. Each steel cable is fixed on the tensioning device, passes through the upper pulley and the movement, returns to the lower pulley, and enters the inner ring located at the lower layer of the wrist watch. Surrounding the movement of tourbillon is high-tech material NTPT (thin layer composite technology) carbon fiber, which is light in texture and strong and durable. NTPT carbon fibers are composed of multiple layers of parallel filaments separated from carbon fibers. These thin layers are first immersed in a resin and then woven by a special machine. The layers are interlaced at an angle of 45 degrees to create a distinctive visual effect. Black rubber strap with NTPT carbon fiber needle clasp.
