V2 upgraded version of Richard Mille Richard Mille RM21-02 series, newly upgraded 6-digit flywheel, equipped with fully automatic imported mechanical movement, size 40x50x16mm, bezel and column made of carbon fiber material as structural support, further strengthening its precision structure. Carbon fiber, 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 21-02 watch is like a real aircraft on the wrist. It uses cutting-edge technology as a surging power to constantly break the shackles of traditional materials on the watchmaking industry. Loaded with Royal Oak quality tape, hollow design, full of technology, following the rules? Keeping a low profile? This has never been Richard Mille's worldview.
