RM factory creates a real aircraft on the wrist. The RM 21-01 aerodynamic tourbillon watch case combines ultra-light and wear-resistant Carbon TPT carbon fiber with 5N red gold material. The bottom plate is made of Haynes 214 material specially used for aerospace engine combustion chambers. The structure of the 5N red gold watch case is very complex. The bezel and column made of Carbon TPT? carbon fiber material serve as structural supports to further strengthen its precision structure. Carbon TPT? carbon fiber material, a lightweight and durable composite material, is made of carbon fiber material through the use of automation. The process stacks hundreds of thin layers of carbon fiber and makes each layer of carbon fiber staggered at a 45-degree angle. It is then heated to 100 degrees in an autoclave, and finally processed with micron precision. This reinforced structure is like armor. The case provides excellent protection and is firmly fixed by 20 spline screws. RICHARD MILLE RM 21-01 Aerodynamic Tourbillon Watch - As the name suggests, the watch is like a real aircraft on the wrist, using cutting-edge technology as a surging Momentum, constantly breaking the shackles of traditional materials on the watchmaking industry.,
