The Richard Mille RM21-01 series is equipped with a fully automatic imported mechanical movement with a size of 40x50x16mm. The bezel and column made of carbon fiber serve as structural supports to further strengthen its precision structure. Carbon fiber material, a lightweight and durable composite material, uses an automated process to stack hundreds of thin layers of carbon fiber, staggering each layer of carbon fiber at a 45-degree angle, then heating it to 120 degrees in an autoclave, and finally Processed with micron precision. This reinforced structure provides excellent protection to the case like armor and is firmly held in place by 20 spline screws. The RICHARD MILLE RM 21-01 watch is like a real aircraft on the wrist. It uses cutting-edge technology as its surging power and constantly breaks the shackles of traditional materials on the watchmaking industry. Loaded with Royal Oak quality tape, hollow design, full of technology, follow the rules? Keeping a low profile? This has never been Richard Mille's worldview.
